HI,

I need a way to remove a folder and all its sub folders and files with php.  

I know i can remove an empty folder with "rmdir", but in this case folder contains 3 subfolders, each of which contain several files, and I want to delete all the contents and the directory.

I 'borrowed' this for you (I left in the originators details so you can thank him if you want though) from php.net document comments for rmdir().

This function builds on the suggestion by davedx, but doesn't keep going on failure.  It also doesn't remove dot-files, since those usually should be deleted explicitly.

Hope that helps you =)

<?php

/**

 * rm_recurse

 * @description Remove recursively. (Like `rm -r`)

 * @see Comment by davedx at gmail dot com on { http://us2.php.net/manual/en/function.rmdir.php }

 * @param file {String} The file or folder to be deleted.

 **/

function rm_recurse($file) {

    if (is_dir($file) && !is_link($file)) {

        foreach(glob($file.'/*') as $sf) {

            if ( !rm_recurse($sf) ) {

                error_log("Failed to remove $sf\n");

                return false;

            }

        }

        return rmdir($file);

    } else {

        return unlink($file);

    }

}

?>

rmdir cannot delete non-empty dir, so you have to delete all subfoldera and files first. For example you can do it with function from code snippet. For more details, please check out http://ru2.php.net/rmdir
<?php

    // dan's comment (http://ru2.php.net/manual/ru/function.rmdir.php#81692)

    function remove_dir($dir)

    {

        if(is_dir($dir))

        {

            $dir = (substr($dir, -1) != "/")? $dir."/":$dir;

            $openDir = opendir($dir);

            while($file = readdir($openDir))

            {

                if(!in_array($file, array(".", "..")))

                {

                    if(!is_dir($dir.$file))

                        @unlink($dir.$file);

                    else

                        remove_dir($dir.$file);

                }

            }

            closedir($openDir);

            @rmdir($dir);

        }

    }

?>
 

// So now you can delete dir with:
 

<?php remove_dir('/path/to/dir/which/has/to/be/deleted');

If minibago's solution will not work, try another (from php.net's):

<?php

function rm_recursive($filepath)

{

    if (is_dir($filepath) && !is_link($filepath))

    {

        if ($dh = opendir($filepath))

        {

            while (($sf = readdir($dh)) !== false)

            {

                if ($sf == '.' || $sf == '..')

                {

                    continue;

                }

                if (!rm_recursive($filepath.'/'.$sf))

                {

                    throw new Exception($filepath.'/'.$sf.' could not be deleted.');

                }

            }

            closedir($dh);

        }

        return rmdir($filepath);

    }

    return unlink($filepath);

}

?>
