The script below loops over the specified directory and chmods its files, directories and subdirectories recursively.

  function chmodDirectory( $path = ‘.’, $level = 0 ){  
    $ignore = array( ‘cgi-bin’, ‘.’, ‘..’ ); 
    $dh = ( $path ); 
    while( false !== ( $file = readdir( $dh ) ) ){ // Loop through the directory 
      if( !in_array( $file, $ignore ) ){
        if( is_dir( “$path/$file” ) ){
          chmod(”$path/$file”,0777);
          chmodDirectory( “$path/$file”, ($level+1));
        } else {
          chmod(”$path/$file”,0777); // desired permission settings
        }//elseif
