A real gem - PHP_CompatInfo

published on December 27, 2010.
Heads-up! You're reading an old post and the information in it is quite probably outdated.

Last night I was pondering how nice would it be to have a tool of some sort, that would simply spit out what version of PHP does my app require. Something like: here are my .php files, what PHP version and/or extensions do I need for it? First I thought about jumping right in and writing it myself, but hey, this kind of a tool sounds way to useful not to be written already! After a bit of a googling there it was: PHP_CompatInfo. A nice PEAR package that can tell me everything I want about my code and even a bit more.

It tells what’s the minimum overall PHP version needed, all the PHP extensions used and the PHP versions and extensions file by file.

Installing PHP_CompatInfo is easy: pear install php_compatinfo and that’s about it. Using it isn’t much harder:


require_once 'PHP/CompatInfo.php';

$source = '/home/robert/www/Zend/';

$driverType = 'xml';
$driverOptions = array();

$info = new PHP_CompatInfo($driverType, $driverOptions);

Include the main PHP_CompatInfo file, set the path to the file or directory you want to check and then just run it. By default it’ll just var_dump the results, which is pretty much OK for a few files and directories. For a library like Zend Framework, I found the XML output to be the best. Besides the var_dumping and XML, there are other options for the output like CSV, a simple HTML table and Text, which is used when using the CLI. Oh, right, you can run it either from the console or from your web browser. PHP_CompatInfo’s documentation is very well written and describes all part of it, so I won’t be bugging you with that.

So yea, this little gem goes right into my box of must have tools.
