$scanner = new NS\Scanner($string);

while (!$scanner->isAtEnd()) {
    $scanner->scanToString('{{');
    $start = $scanner->location();

    if (!$scanner->isAtEnd()) {
        $scanner->scanUpToString('}}');
        $end = $scanner->location();
        echo substr($string, $start, $end - $start); //123456...
