Thanks for the references. I've seen the RFC, but I haven't seen that thread you've linked to. It does contain almost all things I could say here. However, I haven't found very strong argument against decoupling in that thread either. :) Even without short tags, PHP will not be a well-formed XML processing instruction in many cases. For example, <?php $x = '<?>'; ?> or, more commonly: <root test="<?php echo $value; ?>" /> Plain <? has an additional problem of affecting the ability to include XML files from PHP source code. However, it seems to me that using the syntax above will have exactly the same consequences for XML well-formedness as using <?=. Since the syntax above is allowed with short_open_tags off, disallowing <?= with that setting off looks like an overkill. That's my reasoning behind starting this thread, anyway. Admittedly, I haven't said anything new here, but I've rephrased an old argument in a nicer way. :)Maybe it will do some good. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
