PHP Question

Delete directory with files in it?

I wonder, what's the easiest way to delete a directory with all its files in it?

I'm using

rmdir(PATH . '/' . $value);
to delete a folder, however, if there are files inside of it, I simply can't delete it.

Answer

There are at least two options available nowdays.

  1. Before deleting the folder, delete all it's files and folders (and this means recursion!). Here is an example:

    public static function deleteDir($dirPath) {
        if (! is_dir($dirPath)) {
            throw new InvalidArgumentException("$dirPath must be a directory");
        }
        if (substr($dirPath, strlen($dirPath) - 1, 1) != '/') {
            $dirPath .= '/';
        }
        $files = glob($dirPath . '*', GLOB_MARK);
        foreach ($files as $file) {
            if (is_dir($file)) {
                self::deleteDir($file);
            } else {
                unlink($file);
            }
        }
        rmdir($dirPath);
    }
    
  2. And if you are using 5.2+ you can use a RecursiveIterator to do it without needing to do the recursion yourself:

    $dir = 'samples' . DIRECTORY_SEPARATOR . 'sampledirtree';
    $it = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS);
    $files = new RecursiveIteratorIterator($it,
                 RecursiveIteratorIterator::CHILD_FIRST);
    foreach($files as $file) {
        if ($file->isDir()){
            rmdir($file->getRealPath());
        } else {
            unlink($file->getRealPath());
        }
    }
    rmdir($dir);
