Tag <? Misbehaving in PHP

Answer 1

In your php.ini, you need to set the following directive:

short_open_tag = On

From the manual:

Tells whether the short form (<? ?>) of PHP's open tag should be allowed...

If you have time on your hands, you may want to consider replacing all those short tags '<?' with the full-form ones <?php, for better portability (see what just happened to you? :)

Answer 2

If you want to use the short tags: ("<?")

they need to be enabled in you php.ini. See this link.
