Some PHP code to clean the cache very useful when you don't have access to symfony "command line interface" on production server.

file: symfony_cc.php

<?php
function deltree($f)
{
  $sf = realpath($sf);
 
  if (is_dir($f)) {
    foreach(glob($f.'/*') as $sf) {
      if (is_dir($sf) && !is_link($sf)) {
        deltree($sf);
        if (is_writable($sf)) {
          echo 'Delete dir.: '.$sf."\n";
          rmdir($sf);
        }
      } else {
        if (is_writable($sf)) {
          echo 'Delete file: '.$sf."\n";
          unlink($sf);
        }
      }
    }
  } else {
    die('Error: '.$f.' not a directory');
  }
}
 
echo '<pre>';
echo 'Clean symfony cache'."\n";
echo "\n";
deltree('../../cache');
echo '</pre>';
