Before you start

About this tutorial

This tutorial shows how to build Web services in PHP using the PHP Development Tools (PDT) plug-in. The PDT project was released in its 1.0 release version in September 2007 and was followed by a V1.0.2 release in January 2008. The PDT project gives you first-class abilities to edit, debug, and deploy PHP applications in the Eclipse IDE.

Objectives

This tutorial has three main objectives. The first is to become familiar with the PDT project and learn how to create and deploy useful PHP projects. The second is to learn about the philosophy behind contract-first development. Third, this tutorial serves as an informative overview of the basic parts that make up a Web Services Description Language (WSDL) file.

Prerequisites

You should have experience with PHP development.

System requirements

To get the most out of this tutorial, you need to install Eclipse and the PDT plug-in. You must also install the Eclipse Web Standard Tools (WST) subproject.

Note: If you installed the Java™ 2 Platform, Enterprise Edition (J2EE) bundle of Eclipse, you already have WST.

To follow the examples, you need Eclipse and one of the operating systems that Eclipse supports — Mac OS X, Microsoft® Windows®, or Linux®. You also need a Java Runtime Environment (JRE) — at least JRE for Java 5 is recommended.


PDT overview

The PDT project gives you the ability to do PHP development using the Eclipse IDE. It includes many features of the Java editing environment, including syntax highlighting, code templating, perspectives, and file and project wizards.

Install PDT

To install PDT, make sure you have the latest version of Eclipse. Use the built-in software updater to update PDT from the update site. PDT requires the WST subproject, so install WST first if you don't already have it. If you downloaded and installed the J2EE bundle of Eclipse, you already have WST. If you downloaded the Java-only bundle of Eclipse, you must install WST from the Eclipse discovery site.

Figure 1. Installing WST from the Eclipse discovery site

Set up PDT

After installing PDT, there are a couple things you might want to set up, especially if you're using PDT and Eclipse on a computer on which you've already been doing some PHP development. The first configuration is the path to the PHP executable. To set this path, open the Preferences window, and in the left pane, expand PHP, then click PHP Executables. In the right pane, you'll see where you can type or browse to the path of your PHP executable file.

Figure 2. Setting up the PHP interpreter
Setting up the PHP interpreter

Under PHP in the left pane, click PHP Interpreter, then, specify the version of PHP you're using. The default is PHP V5.

To access the PHP editor, under PHP in the left pane, expand Editor. The PHP editor that comes with PDT includes many features of the Java editor, including syntax highlighting, formatting, code completion, and code templates.

The PHP Functions tab

The PHP Functions tab shows the common PHP functions and classes available in your library path. You can search for functions in the list by starting to type in the search box, as shown in Figure 3. Double-click the name on the PHP Functions tab to insert the name into the editor at the current cursor position. You can also use code completion (Ctrl+Space) when typing in the editor to pick from a list of matching functions or templates and insert them.

The PHP Project tab

The PHP Project tab provides a PHP-centric view of your PHP project by listing the contents of your project split into object types. You see any classes you have defined in your project under Classes and any functions under Functions. Double-click the item on the PHP Project tab to automatically navigate to the item in the editor in which it's found. Figure 4 shows an example of the PHP Project tab with the classes and functions discussed later.

The PHP Explorer

The PHP Explorer shows a list of the projects and files in your workspace. It's consistent with the other project explorers, such as the Java Explorer.


Building a service contract

WSDL overview

A WSDL file is an XML file that describes one or more Web services. The description includes everything from the methods, or operations, available in the service to the schema for the messages that form the inputs and outputs of the operations.

If you're familiar with WSDL files or already have one that you want to use and don't care how they work, you can safely skip this section and move on to "Alternative: Import a WSDL file." But if you're new to WSDL files or have used them before, but would like a refresher, this section will be very helpful.

The ability to visually build WSDL files and XML Schema Definition (XSD) files in Eclipse should be a great help when building WSDL files in Eclipse. If you'd like, you can always switch the WSDL editor to Source mode to edit the source yourself. The WSDL file includes four major parts, which are described at a high level below and explored in greater detail in the rest of this section.

types
This section of the WSDL file covers the types used in the Web service request and response messages.
message
This contains the messages sent to and received from the Web service. In the visual Eclipse editor, they are shown as the input and output of the Web service operation.
portType
This lists the operations the Web service exposes.
binding
This includes the communication protocols the Web service uses.
service
This describes the service or services exposed.

The types element

The types element can contain information about the types used in the SOAP messages. The types are conveniently described in XML schema, and you can import other types. The Eclipse editor works well with both. One advantage of using external schemas is that you can reuse complex types that have already been defined. In contrast, an advantage of using inline (that is, inside the WSDL) schema is that your WSDL file contains everything that needs to be known about the Web service.

Note: To keep things simple, this tutorial focuses on defining types in inline schema.

The message element

The message element defines the messages sent in and received from the operations. If you think of a Web service operation as being a method in PHP code, the message element describes the parameters sent into the method and the return type that the method returns.

The portType element

The portType element describes the operations a Web service exposes. If you think of a Web service, again, as a PHP class, the portType element would be explaining the public methods the PHP class exposes.

The binding element

The binding element explains how the operations are exposed in terms of which protocol is used to access them. In most of the examples you find, the SOAP protocol is used to access Web service operations. However, other protocols may be used, such as HTTP.

The service element

The service element describes the Web service, allowing you to group similar operations in a collection of operations that make sense as a service.

Contract-first development

Building or providing a WSDL file first, then writing the code to implement the service according to the WSDL file (contract) is called contract-first development. Building the contract before worrying about how you're going to implement it has a few advantages.

Open implementation
It leaves you free to implement the service however you see fit. As long as you comply with the contract, it doesn't matter if you build the Web service in the PHP, Java, Groovy, or any other language.
Concurrent development
If you build the contract first, you can give the contract out to your consumers so they can start developing clients to call the services. As long as you comply with the contract you've given to your consumers, you both can build your code concurrently. If you did bottom-up Web service development, in which you build the code first, then expose the contract for the service, other people are waiting for you to finalize your code base.
Proper analysis
Creating the contract first keeps you and your team honest by performing analysis up front because the analysis leads to the content of the contract. If you build the Web service from the bottom up, there's a greater likelihood that your service grows organically, and you could end up with a contract more specific to your implementation than you might intend.

Building the WSDL file visually

Build the file in the WSDL visual editor

When you build a WSDL file visually in the Eclipse WSDL visual editor, it feels natural, given the visual editor layout, to build the WSDL file starting at the service element and working backward, defining the types last. The editor first shows you a UI element that actually corresponds to the service element in the WSDL file.

Figure 5 shows part of the Web service. Because the example is a Web service that returns the manufacturer's recommended tire sizes given the year, model, and make of an automobile, call the service myTireService. You can type the new name directly into the visual editor.

Figure 5. The Web service in the WSDL file
The Web service in the WSDL file

Listing 1 shows the change Eclipse makes for you in the WSDL source.

Listing 1. The WSDL changes to service
<wsdl:service name="myTireService">
	<wsdl:port binding="tns:myTireServiceSOAP"
		name="myTireService">
		<soap:address
			location="http://localhost/~nagood/phpws/service.php" />
	</wsdl:port>
</wsdl:service>

The Outline tab displays the major parts of the WSDL file. As you click the parts on the Outline tab, they're highlighted in the WSDL visual editor.

Figure 6. The Outline tab
The Outline tab

Update the name of the default operation

After changing the name of the service, you can update the name of the default operation that was created when Eclipse initially built the skeleton WSDL file. Click NewOperation and start typing the name of the method. The name of the method in this example is getRecommendedTireSpecs, as shown in Figure 7. The updated WSDL source is shown in Listing 2.

Figure 7. The operation in the WSDL editor

Listing 2. Updated WSDL source for getRecommendedTireSpecs
<wsdl:portType name="myTireService">
	<wsdl:operation name="getRecommendedTireSpecs">
		<wsdl:input message="tns:getRecommendedTireSpecsRequest" />
		<wsdl:output message="tns:getRecommendedTireSpecsResponse" />
	</wsdl:operation>
</wsdl:portType>

The Outline tab is updated along with the visual editor, as shown in Figure 8.

Figure 8. The Outline tab after editing the operation

Leave the binding alone for now. It's defined as it should be, and there's no reason to change it. However, in this example, the types of the request and response will be augmented from the default type of strings.

Edit request and response types

On the input line of the WSDL visual editor, click the blue arrow next to the generated request element name getRecommendedTireSpecs. The Eclipse visual XML schema editor opens for you automatically, allowing you to edit the complex types for the request and response. The request is shown in Figure 9, with the elements added for the year, make, and model of the automobile.

Figure 9. The getRecommendedTireSpecs request object
The getRecommendedTireSpecs request object

Right-click the type, then click Refactor > Make Anonymous Type Global to be able to reuse the complex type elsewhere in the WSDL file. A global type is not necessary for purposes of this example, but it's helpful to see the difference. Listing 3 shows the type after it was made into a global type.

Listing 3. After making the type a global type
<!-- ... parts of the WSDL before ... -->
<xsd:element name="recommendedTireSpecsRequest" type="tns:automobileType"></xsd:element>
<xsd:complexType name="automobileType">
		<xsd:sequence>
			<xsd:element name="year" type="xsd:int"></xsd:element>
			<xsd:element name="make" type="xsd:string"></xsd:element>
			<xsd:element name="model" type="xsd:string"></xsd:element>
		</xsd:sequence>
</xsd:complexType>

Go back to the WSDL editor and click the blue arrow next to the output line. The schema editor opens once again, this time with the element and anonymous type displayed. Because the example service returns one or more sets of tire specifications, each consisting of the speed rating, traction rating, temperature rating, and dimensions of the tire, the simple string in the return type is not adequate.

Add the data parts as attributes

This time, instead of adding elements to the complex type, add the different data parts as attributes. Remove the element that's there, then add attributes for speedRating, tempRating, tractionRating, width, ratio, and radius.

Figure 10. After adding the attributes
After adding the attributes

Add another complex type called tireSpecificationsType. This is just a collection of tireSpecificationType complex types.

Figure 11. The tireSpecificationsType
The tireSpecifcationsType

Now change the recommendedTireSpecsResponse to make it of type tireSpecifcationsType. When you're done, it looks like Figure 12. Now, you have all the types you need to use the Web service. The final WSDL file looks like Listing 4.

Validating the Web service

Alternative: Import a WSDL file

If you don't need to build a WSDL file for your Web service because you already have one, you can import the WSDL file into Eclipse. After doing so, you can still validate it or see it visually using the WSDL visual editor.

Validate the Web service in Eclipse

After you're finished with the WSDL file, validate it inside Eclipse to make sure it's a valid WSDL file. Choose Validate from the context menu of the project in PHP Explorer to validate the file with Eclipse. As long as the file is valid, you're ready to start building the PHP Web service.


Building the PHP service code

Using SOAP extensions

The SOAP extension in PHP allows you to build SOAP clients and servers in PHP. To build the SOAP client, you use primarily the SoapClient class in PHP. In addition to the SoapClient class, there are classes to build SOAP servers (SoapServer) and classes for dealing with SOAP messages (SoapHeader, SoapFault, SoapParam, and SoapVar). For more information about these classes, see the links to the PHP SOAP documentation in Resources.

In V4 of PHP, the SOAP extensions were an optional addition. To use SOAP extensions, you had to either enable the extensions with the --enable-soap option or look for precompiled distributions of PHP that already had the SOAP extension enabled. In PHP V6, the SOAP extension is enabled by default.

SOAP extensions with PHP

If you're unsure whether you have SOAP extensions enabled for your version of PHP, there are a couple ways to tell. The first is to write a quick PHP file containing only <?php phpinfo(); ?> and view it in a browser or execute it from the command line. Alternatively, you can use the command-line option -m, which shows the compiled-in modules for PHP.

As long as you have SOAP extensions enabled, you can create a SoapServer dynamically, without having to worry about serializing your PHP objects to XML or deserializing them from XML to your PHP classes.

The Web service used in this tutorial demonstrates how to build a PHP Web service with a slightly more complicated WSDL and class structure over a standard echo or Hello World service that takes a string and returns a string. To build this service, the PHP code must include some objects that are mapped to the complex types in the WSDL file by the SOAP extension code.

The supporting classes

In the PHP service code, although you don't have to worry about serializing and deserializing objects to and from XML, you should build classes that correspond to the types in the WSDL file. There are projects written in PHP that help with this a bit, but with only three types in this service, the effort is fairly trivial.

Build the Automobile class

The first class to build in the PHP code is the Automobile class. It actually maps to the automobileType, but thanks to the ability to specify the mapping while creating the PHP SoapServer, you don't have to make the names of the classes in PHP map to the names of the complex types in the WSDL file. This can make the PHP code look more like PHP code, as it's common to follow Pascal or upper-camel naming conventions for classes in PHP. In contrast, if you've done some surfing on the Web, you'll see many examples in which people keep the names of the PHP classes the same as the complex types in the WSDL file, presumably because it makes it easier to remember what's associated with what.

The Automobile PHP class is shown in Listing 5. The fields exposed as elements in the WSDL file are public fields in the class. Note the absence of accessors in the class.

Listing 5. The Automobile PHP class
class Automobile {
    public $year; // int
    public $make; // string
    public $model; // string
}

Build the TireSpecification class

The second class is the TireSpecification class. In the type definition in the WSDL file, the fields for speedRating, tempRating, and others are attributes. In the PHP class, they're still defined as public fields, just like in the Automobile class in Listing 5.

Listing 6. The TireSpecification class
class TireSpecification {
    public $speedRating; // string
    public $tempRating; // string
    public $tractionRating; // string
    public $width; // int
    public $ratio; // int
    public $radius; // int
}
Listing 7. The WSDL definition for automobileType
<xsd:complexType name="automobileType">
<xsd:sequence>
	<xsd:element name="year" type="xsd:int"></xsd:element>
	<xsd:element name="make" type="xsd:string"></xsd:element>
	<xsd:element name="model" type="xsd:string"></xsd:element>
</xsd:sequence>
</xsd:complexType>

Build the TireSpecificationList class

Finally, the TireSpecificationList class contains one field, which holds an array of TireSpecification objects. This maps back to the tireSpecificationsType in the WSDL file and will be the value returned from the function that handles the Web service.

Listing 8. The TireSpecificationList class
class TireSpecificationList {
    public $tireSpecification; // tireSpecificationsType
}

The complex types all have corresponding PHP classes, so the code is nearly complete. If you look at the PHP Project tab, you will see the list of new classes. All that's left in the code is to add a class to be the service and some code to tell the SoapServer how to handle the WSDL.

Build the service class

The service class is a lightweight class that contains the method mapping to the operation name in the WSDL file. The operation is shown in Listing 9. Note that the names are the same and that the function takes a single parameter, which will be an Automobile object.

Listing 9. The WSDL operation
<wsdl:binding name="myTireServiceSOAP" type="tns:myTireService">
<soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" />
<wsdl:operation name="getRecommendedTireSpecs">
    <soap:operation
        soapAction="urn:myTireService#getRecommendedTireSpecs" />
    <wsdl:input>
        <soap:body use="literal" namespace="urn:myTireService"
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
    </wsdl:input>
    <wsdl:output>
        <soap:body use="literal" namespace="urn:myTireService"
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding" />
    </wsdl:output>
</wsdl:operation>
</wsdl:binding>

To keep things simple, I hard-coded a couple of tire specifications for my car, a 1993 Nateauto Speedster (OK — that's a really corny name, but I'd rather be accused of having a poor imagination for marketing than trademark infringement). I made up a rule that if the car is older than 1994, a smaller tire is among the recommend tire sizes.

Add the server code

Finally, the server code is listed at the end of your service.php file. The SoapServer is instantiated with the class map and a couple of options.

Listing 10. The SoapServer code
$server = new SoapServer('myTireService.wsdl',
array('classmap' => $classmap,
    'soap_version' => SOAP_1_2,
    'uri' => 'urn:myTireService',
    'style' => SOAP_RPC,
    'use' => SOAP_LITERAL));

$server->setClass('myTireService');
$server->handle();

Table 1 shows the options for creating this code.

Table 1. Options for creating SoapServer
Key nameWhat it does
classmap An associative array that links the complex type names from the WSDL file to the PHP class names
soap_version The version of the SOAP specification that SoapServer supports
uriThe Universal Resource Identifier (URI) used as the namespace for the service (You will see urn:myTireService in the WSDL file.)
styleThe style of WSDL method binding used (In this example, RPC literal is used.)
useThe type of binding to use, which can be one of SOAP_LITERAL ("literal") or SOAP_ENCODED ("encoded")

The myTireService class is set so that when the handle() method handles the post, the getRecommendedTireSpecs() function is called.


Deploying the code

Add a builder for your project

Although the PDT tools allow you run PHP scripts and execute PHP Web pages given a server runtime, neither one helps too much with testing Web services because you need to post a SOAP request to the Web service and be able to see the response. So, the goal is to be able to publish the service.php file and myTireService.wsdl file to a Web location from which you can call them from a test SOAP client.

You really shouldn't put your workspace under the document root or a folder published by the Web server because of permissions and security. The best alternative is to put a builder into Eclipse that publishes your files to the Web document location of your choice. To add a new builder for your project, click Properties from the context menu for your project.

In the left pane, click Builders. Click New to add a new builder for your project.

Figure 13. Adding a new builder

In the Choose configuration type window, select Program from the list, then click OK.

Type the name of a builder — for example, ServicePublisher. In the Location field, type the name of a copy command appropriate for your operating system, like /bin/cp.

Figure 15. Configuring the new builder to deploy your service

Beneath the Arguments field, click Variables, then select the variable called ${project_loc} as the base of your project. Remember that you will have to type the names of the actual files in this Arguments field. You can't use wildcards like the asterisk (*) or question mark (?) because these are interpreted by your shell before being sent to the command line. As far as /bin/cp is concerned, there is no file called * or ?.

Troubleshooting

Another alternative: REST services

Representational State Transfer (REST) is an architecture or style of using Web services, not a standard like SOAP. REST Web services are simple and can use any other standard, like HTTP or XML. The Internet (basically) is a huge collection of REST services, where you make the request by supplying a URL to a server and receive a document as a response. Common technologies, such as Atom or RSS feeds, are REST services.

As an alternative to using SOAP services, you can build Web services in PHP. You can use existing PHP and PEAR objects, such as SimpleXML, XMLReader, and XMLWriter included in PHP V5 (see Resources).

For troubleshooting steps, a good SOAP client that gives you all the SOAP faults helps. If your existing SOAP client swallows errors, consider using a different one. Other useful tools are those like Fiddler (see Resources) or other proxy applications that trap the messages sent to and from the Web service.

When I built the WSDL file for the first time, I wasn't paying attention and created the WSDL using document literal. While this is great practice for creating WSDL files, I had nothing but problems trying to get it to work, even with the PHP SoapServer class set to use SOAP_DOCUMENT and SOAP_LITERAL. The error that I received when the WSDL was set up as document literal was:

 Procedure 'getRecommendedTireSpecs' not present.

After changing the WSDL to use RPC encoded, I got the error:

 Error cannot find parameter.

I was able to make it go away be ridding the automobileType of all but one element (the year). I finally changed the WSDL to use RPC literal, which is fully Web Services Interoperability Organization (WS-I)-compliant, as well as allowing me to use the rich, complex types I had set up.


Summary

Creating a WSDL file first, then the service, is doing contract-first development. With Eclipse, PDT, and WST, you have the tools you need to create the WSDL visually and easily, then use Eclipse's features to automatically publish your PHP service to a location.

The PDT project gives you the ability to write PHP code with first-class IDE features. Using the PHP perspective, you can navigate your PHP project more easily. With these tools and the built-in support in PHP for SOAP and XML, you can create PHP Web services with little effort.
