syntax - Difference between <?php and <?

Question

I am new to php and would like to know if there are any differences between these server tags :

<?php
?>

and

<?
?>

Answer 1

The first is a safe open and close tag variation, the second is the so called short-open tag. The second one is not always available, use the first option if it's possible. You could check the availability of short open tags in php.ini, at the short_open_tag.
