I bought a php script on Code canyon, and it was running ok on my localhosts, but when i uploaded the files to digital ocean, i noticed that the .php files where not being executed, after some investigation i discovered that my server does not recognise the php files, because they start with just <?, instead of <?php.

*Is it possible to change PHP to execute .php files that start with just <? *

I running ubuntu 14.04, with php 5.5.9

Thanks!
