Support short PHP tags

[bitwiseman]

PHP now allows <? ... ?> tags. We currently only recognize <?= and <?php as the start of php tags.

Note: the allowed pattern will need to be <?_ (with a space) to avoid collision with <?xml tags and the like.

Who can point me into the right direction? We have a news site with a java script scroller, how can I get the images big once someone hovers over the image?
