I see many good reasons to disable short open tags. However, there is a
compromise that is better from all vantage points:
<ul>
<?p foreach ($items as $item): ?>
<li><?=$item ?></li>
<?p endforeach ?>
</ul>
<?p is a valid PI and would prevent <?xml from being parsed as PHP.
Also legal is <?: as PI's can start with or contain : or _. Honestly
though, this is not so important to me, my primary concern is the
conflict with <?xml. I mention it out of deference for those who
actually do care about writing scripts that are xml-compliant for some
strange reason :). Also possible and relatively simple to implement
would be to allow an = at the start of an expression to alias to T_ECHO,
so that <?p =$item ?> would work like <?=$item?>. This is, however,
very perl-ish, so I mention it only as a possible way to preserve that
aspect of short tags for template usage. God forbid we start seeing
regular scripts using "=" to mean "echo" :).
As a note, I use exclusively <?php in my templates and also use <?xml to
generate xhtml, so I am very much against per-script enabling of short
tag <? for the annoyance it would introduce of forcing an ini_set() at
the top of each template and the bottom as well to be a good citizen and
restore the old value.
