The correct way to delete all files older than 2 days in PHP

Question

Just curious

        $files = glob(cacheme_directory().\"*\");
        foreach($files as $file)
        {
            $filemtime=filemtime ($file);

Here is an example of how to do it recursively.

function remove_files_from_dir_older_than_x_seconds($dir,$seconds = 3600) {
    $files = glob(rtrim($dir, '/')."/*");
    $now   = time();
    foreach ($files as $file) {
        if (is_file($file)) {
            if ($now - filemtime($file) >= $seconds) {
                echo "removed $file
".PHP_EOL;
                unlink($file);
            }
        } else {
            remove_files_from_dir_older_than_x_seconds($file,$seconds);
        }
    }
}

remove_files_from_dir_older_than_x_seconds(dirname(__file__).'/cache/', (60 * 60 * 24 * 1) ); // 1 day
