PHP Recursive Backup of Directories

This script can be used to make backup of entire directories and subdirectories in our servers, you can use the script in conjunction with cronjobs

//specify the source dir and target dir
$src = $_SERVER['DOCUMENT_ROOT'].'/test/backup/dir1';
$dst = $_SERVER['DOCUMENT_ROOT'].'/test/backup/dir2';

function recurse_copy($src,$dst) { 
    $dir = opendir($src); 
    @mkdir($dst); 
    while(false !== ( $file = readdir($dir)) ) { 
        if (( $file != '.' ) && ( $file != '..' )) { 
            if ( is_dir($src . '/' . $file) ) { 
                recurse_copy($src . '/' . $file,$dst . '/' . $file); 
            } 
            else { 
                copy($src . '/' . $file,$dst . '/' . $file); 
            } 
        } 
    } 
    closedir($dir); 
} 

//execute the command
recurse_copy($src,$dst);

If you want to remove the old content from the directory you can use this recursive function that removes all files and folders from the specified directory

  function rrmdir($dst) {
  if (is_dir($dst)) {
    $objects = scandir($dst);
    foreach ($objects as $object) {
      if ($object != "." && $object != "..") {
        if (filetype($dir."/".$object) == "dir") 
           rrmdir($dir."/".$object); 
        else unlink   ($dst."/".$object);
      }
    }
    reset($objects);
    rmdir($dir);
  }
 }
