Get the md5 of your whole PHP application
<?php
function glob_recursive($pattern, $flags = 0) {
$files = glob($pattern, $flags);
foreach (glob(dirname($pattern).'/*', GLOB_ONLYDIR|GLOB_NOSORT) as $dir) {
$files = array_merge($files, glob_recursive($dir.'/'.basename($pattern), $flags));
}
return $files;

Ever wondered how many lines you've written in your PHP project ? This is almost the most useless script in history but I'm kinda curious so I wrote it anyway...
<?php
set_time_limit(0);
function glob_recursive($pattern, $flags = 0) {
$files = glob($pattern, $flags);
foreach (glob(dirname($pattern).'/*', GLOB_ONLYDIR|GLOB_NOSORT) as $dir) {
$files = array_merge($files, glob_recursive($dir.'/'.basename($pattern), $flags));
}
return $files;
