Information on the minimum required version of PHP of each component of Zend Framework

German: Dieser Artikel ist auf Englisch, da er an ein internationales Publikum gerichtet ist.

In one of the latest posts on the Zend Framework maillinglist there was a question regarding the minimum required version of PHP for the current version Zend Framework (1.9.0). As of Version 1.7.0 of ZF the documentation recommends versions >=5.2.4 for PHP. Some users are stuck with php5.1.6 (e.g. those running Redhat Linux) and these need to know the components that could be problematic.

To see the minimum required version of PHP for each package of ZF, i’ve created a shellscript which uses PHP_CompatInfo from Pear. It doesn’t take the dependencies into account!

For your convinience i’ve created a website with these infos:

By the way for all users of Redhat with PHP 5.1.6: In Zend 1.9.0 the following files that need a higher version than 5.1.6. Be aware, that some components are dependend on these files, e.g. Zend_Cache_Backend is used in about 40% of all components (see comment by Thomas below).

ZendCacheBackend.php : 5.2.1
ZendCryptDiffieHellman.php : 5.2.0
ZendCryptRsaKeyPrivate.php : 5.2.0
ZendCryptRsaKeyPublic.php : 5.2.0
ZendCryptRsa.php : 5.2.0
ZendFileTransferAdapterAbstract.php : 5.2.1
ZendNavigationPage.php : 5.2.0
ZendOpenId.php : 5.2.0
ZendPdfPage.php : 5.2.0
ZendPdf.php : 5.2.0
ZendTestPHPUnitDbOperationTruncate.php : 5.2.1

Thanks to Stefan Sturm for this list!

Still, you should run your own tests and check if your application is really working. The Website above just shows the possiblity to run a specific component under a specific php-version and isn’t taking dependencies between components into account. Or simply update to the current version of PHP 😛

  1. You did not take into account the dependencies.
    Zend_Cache_Backend is the base file for Caching. Caching is used in about 40% of all components.

    And you should also note that 5.1.6 has known problems (which were the reason why we raised the MRV to 5.2.4).

    Such an statement can only be given for a specific php version, on a specific OS when running the testbed and own application tests.

    1. You are right, i didn’t take dependencies into account. And of course i want to encourage users to do their own testing! I’ve updated the article to make that clear.

      Thanks for all your input, but i think this goes beyond the scope of this small website to take dependencies into account.
