• Delete directory with files in it? 31 answers

I need a script which can remove a whole directory with all their subfolders, files and etc. I tried with this function which I found in internet before few months ago but it not work completely.

function deleteFile($dir) {
    if(substr($dir, strlen($dir)-1, 1) != '/') { 
        $dir .= '/'; 
    }
    if($handle = opendir($dir)) { 
        while($obj = readdir($handle)) { 
            if($obj != '.' && $obj != '..') { 
                if(is_dir($dir.$obj)) { 
                    if(!deleteFile($dir.$obj)) {
                        echo $dir.$obj."<br />";
                        return false;
                    }
                }
                elseif(is_file($dir.$obj)) { 
                    if(!unlink($dir.$obj)) {
                        echo $dir.$obj."<br />";
                        return false;
                    }
                }
            }
        }
        closedir($handle); 
        if(!@rmdir($dir)) {
            echo $dir.'<br />';
            return false;
        }
        return true;
    }
    return true;
}

For the test I use a unpacked archive of prestashop and I try to delete the folder where archive is unpacked but it doesn't work.

/home/***/public_html/prestashop/img/p/3/
/home/***/public_html/prestashop/img/p/3
/home/***/public_html/prestashop/img/p
/home/***/public_html/prestashop/img

These are the problem folders. At the first time I think - "May is a problem with the chmod of the files" but when I test with all files chmod permission 755 (after that with 777) - the result was the same.

/**
 * Deletes a directory and all files and folders under it
 * @return Null
 * @param $dir String Directory Path
 */
function rmdir_files($dir) {
 $dh = opendir($dir);
 if ($dh) {
  while($file = readdir($dh)) {
   if (!in_array($file, array('.', '..'))) {
    if (is_file($dir.$file)) {
     unlink($dir.$file);
    }
    else if (is_dir($dir.$file)) {
     rmdir_files($dir.$file);
    }
   }
  }
  rmdir($dir);
 }
}

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

Try out the above code from php.net

Worked fine for me

Answer 3

The easiest and the best way using the system() method

$dir = dirname ( "/log" );
if ($handle = opendir($dir)) {
    while (( $file = readdir($handle)) !== false ) {
        if ($file != "." && $file != "..") {
            system("rm -rf ".escapeshellarg($dir.'/'.$file));
        }
    }
}
closedir($handle);

Answer 4

function delete_files($dir) { 
  foreach(glob($dir . '/*') as $file) { 
    if(is_dir($file)) delete_files($file); else unlink($file); 
  } rmdir($dir); 
}

Answer 5

You can use a cleaner method for doing a recursive delete of a directory.

Example:

function recursiveRemove($dir) {
    $structure = glob(rtrim($dir, "/").'/*');
    if (is_array($structure)) {
        foreach($structure as $file) {
            if (is_dir($file)) recursiveRemove($file);
            elseif (is_file($file)) unlink($file);
        }
    }
    rmdir($dir);
}

Usage:

recursiveRemove("test/dir/");
