Supercharge your PHP serverless applications

IBM Cloud Functions added support for PHP 7.1 last year, and with the release of 7.2, we are updating! With PHP 7.2 you can ensure better app performance. In addition to lowering your total cost of ownership (TCO), you can improve your user experience by taking advantage of faster response times for blocking requests.

When is 7.2 available?

Now! To update your version, all you need to do is re-deploy your actions by using php:7.2 in your code. This can be done through the CLI or through the GUI. If you’re on version 7.1, you’ll want to make the update as soon as possible as PHP 7.1 has already been deprecated. When 7.1 is removed from the service, which will happen very soon, any support requests will be redirected to the PHP 7.2.

How fast?

There are significant changes in speed between 7.1 and 7.2. You should be able to see the improvements in both cold and warm invocations for you PHP 7.2 actions. Check out the following chart to see a comparison of a hello world action that uses 256MB in both PHP 7.1 and 7.2.

New to IBM Cloud Functions?

Excellent! Welcome aboard. The best way to try out the service or get started quickly is to use a hello world action. To read more about using PHP and Functions, check out the docs.

  1. Download the IBM CLI and the Functions plugin.

  2. Create a file called hello.php that contains the following code:

    function main(array $args) : array
    $name = $args["message"] ?? "World";
    $greeting = "<h1>Hello World</h1>";
    return ["body" => $greeting];
  3. Deploy your action as a web action:

    ibmcloud fn action update helloPHP hello.php --kind php:7.2 --web true
  4. Get the URL for the web action and open it in your browser by running the following command.:

    ibmcloud fn action get helloPHP --url
