Hello Reader's If you want to delete a folder and all the files in it then by using PHP recursive function you can do it.

Let's see on example as follows:-

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);
}
