I am using

• Apache 2.2.14 (IPV6 enabled)
• MySQL 5.1.41 (Community Server) with PBXT engine 1.0.09-rc
• PHP 5.3.1 (PEAR, Mail_Mime, MDB2, Zend)

and i am running php files, that i code with <? ?> tags not <?php ?>. but the apache server won't execute my code, but if i try with <?php ?> tags, the code works. Anyone know how to enable the server to execute php code with <? ?> tags ?

you need to configure you php.ini fiile and set short_open_tag to 1
