What kind of miracles happen in if in php?

Question

PHP

I'm in aha. The code:

function tvcap($tvname) {
    global $modx;
    if ($tvname == 0) {
        return 'Err. tvname=' . $tvname;
    }
    $tv = $modx->getObject('modTemplateVar', array('name' => $tvname));
    return $tv->get('caption');
}

Conclusion

Err. tvname=tv_fistashka

How so?
