Okay, after thinking about it, and looking at the replies, it seems as though there is only one situation where the short tags break things, and that's in XML with the <? ?> pair being valid for XML. Yes, enabling the short tags is in the ini file, but is it on by default and require effort to change? That's the real question, I think. Not, why shouldn't I use them the way they are, but why is it that the <?= ?> tag isn't designed into the language to be acceptable? Honestly, the <? ?> pair just feels a little lazy, since all you save are the 4 characters "php ", and all the code inside is the same. The <?= ?> tag gives you 7 characters free and does something unique. The situation I think of using it the most in is something such as: <li><a href="<?= $post->permLink; ?>">...</a></li> Which looks cleaner, in my opinion, than: <li><a href="<?php print $post->permLink; ?>">...</a></li> Not a whole lot larger, no, and perhaps you might say, Well, the second way is more explicit! Yes. Also, shouldn't it be possible to check for <?= ?> and, based on the '=' there, pop out of the parser if it comes across <?xml...?> ?
