Is there a way to test if php code is php < 5.3.2 compatible

So I'm running XAMPP with php5.6.3 installed. However, I'm writing something for a website running on a server using php 5.2.

Is there anything like PHPUnit or PHPCodesniffer (or an online tool) which will tell me if part of my code won't work on specific versions of php (such as php < 5.3.2)?

Thanks

Ok. So after looking into all of the above suggestions I've settled on PHPCompatibility by Wim Godden. https://github.com/wimg/PHPCompatibility

Two reasons I chose this over PHP53Compat_CodeSniffer is:

  1. it specifically has a new feature for what I wanted. Taken from Wim's blog:

You can also test for backwards compatibility of your code by specifying versions like 5.2, which causes it to check whether you’re using functions or keywords not known to this older version. Quite nice if you’re coding on PHP 5.5, but your system engineer tells you half way through the project the project will have to be deployed on 5.2.

That's exactly my case. And...

  1. It uses composer and is much simpler to use than PHP53Compat_CodeSniffer.

CodeSniffer will do:

Download the latest release at http://github.com/wimg/PHP53Compat_CodeSniffer/downloads – make sure you rename the PHP53Compat_CodeSniffer directory to PHP53Compatibility If you have git, use :

git clone git://github.com/wimg/PHP53Compat_CodeSniffer.git PHP53Compatibility

Copy the PHP53Compatibility directory to {your pear path}/PHP/CodeSniffer/Standards

How to run

Start PHP_CodeSniffer like this :

phpcs --standard=PHP53Compatibility <path-to-your-PHP-source-directory>

Sample output

FILE: C:\temp\bla.php
