A simple script to change folder & file permissions of Web Applications like WordPress, Magento etc.

cleanup.php

<?php
//Put this file on the installation folder and run script via browser. This script will change all folders permission as 755 & all file's permission as 644.

//Function to set file permissions to 0644 and folder permissions to 0755
function AllDirChmod( $dir = "./", $dirModes = 0755, $fileModes = 0644 ){
   $d = new RecursiveDirectoryIterator( $dir );
   foreach( new RecursiveIteratorIterator( $d, 1 ) as $path ){
      if( $path->isDir() ) chmod( $path, $dirModes );
      else if( is_file( $path ) ) chmod( $path, $fileModes );
  }
}

echo "----------------------- CLEANUP START -------------------------<br/>";
$start = (float) array_sum(explode(' ',microtime()));
echo "<br/>*************** SETTING PERMISSIONS ***************<br/>";
echo "Setting all folder permissions to 755<br/>";
echo "Setting all file permissions to 644<br/>";
AllDirChmod( "." );

$end = (float) array_sum(explode(' ',microtime()));
echo "<br/>------------ Files and folders permission changed in:". sprintf("%.4f", ($end-$start))." seconds ---------<br/>";
?>

Works very well, thanks!
