PHP: Remove directory and its contents

gistfile2.txt

/**
 * Remove the directory and its content (all files and subdirectories).
 * @param string $dir the directory name
 */
function rmrf($dir) {
    foreach (glob($dir) as $file) {
        if (is_dir($file)) { 
            rmrf("$file/*");
            rmdir($file);
        } else {
            unlink($file);
        }
    }
}

//OR
To delete all files in a folder:
array_map('unlink', glob("$dirname/*.*"));

And then we can remove the folder:
rmdir($dirname);
