Try SplIterators

// setup timezone and get timestamp for yesterday
date_default_timezone_set('Europe/Berlin'); // change to yours
$yesterday = strtotime('-1 day', time());

// setup path to cache dir and initialize iterator
$path      = realpath('/path/to/files'); // change to yours
$objects   = new RecursiveIteratorIterator(
                 new RecursiveDirectoryIterator($path));

// iterate over files in directory and delete them
foreach($objects as $name => $object){
    if ($object->isFile() && ($object->getCTime() < $yesterday)) {
        // unlink($object);
        echo PHP_EOL, 'deleted ' . $object;
    }
}

Creation Time is only available on Windows.
