I’m happy to share that PHP 5.4 is now available in Windows Azure Web Sites! You have always been able to install a custom PHP runtime in Web Sites, but now you can have PHP 5.4 available with the click of a button. And, you can customize the runtime (add/enable extensions, modify configuration settings). Details are in the instructions and links below…

1. Create a website. Any of the following articles will walk you through how to do this.

2. Click on the name of your site in the Windows Azure Portal:


3. Browse to the CONFIGURE tab, and select PHP 5.4 (notice that PHP 5.3 is enabled by default):


4. Click SAVE at the bottom of the screen:


If you browse to a script that calls phpinfo(), you should see this:


Of course, you can always revert back to PHP 5.3. And, you can still customize the built-in PHP runtime, or you can provide your own customized PHP runtime: How to configure PHP in Windows Azure Web Sites.

As always, we’d love to hear your feedback.

  • Can I run ionCube with this version of PHP? It requires being able to specify ZEND_EXTENSION somehow. Do I still need my own standalone implementation of PHP for that?

  • Hi Mike: I haven't tried to enable ionCube with this version of PHP. Have you tried enabling a Zend extension as shown in this post (can't recall if I mentioned this in the forums): That post shows how to enable XDebug, also a Zend extension.

  • Mike,

    My PHP website is attempting to make a call to a compiled program and is failing with the error exec(): Unable to fork. Searching around shows that this is probably a permissions issue, and that I could provide the proper permissions to the IUSR account, but Azure websites don't allow this level of control. Is it possible for PHP to make a call to a compiled program in azure websites?

  • I meant to address Brian, sorry about that. Thanks in advance for your help Brian...

  • Thanks for Your instructions.....

    I understand
