[Edit] Short-Tags Syntax
For less motivated typists, an even shorter delimiter syntax is available. Known as short-tags, this syntax forgoes the php reference required in the default syntax. However, to use this feature, you need to enable PHP’s short_open_tag directive. An example follows:
<?
print "This is another PHP example.";
?>
Caution Although short-tag delimiters are convenient, do not use them when creating PHP-driven software intended for redistribution. This is because this feature could potentially be disabled within the php.ini file. When short-tags syntax is enabled and you want to quickly escape to and from PHP to output a bit of dynamic text, you can omit these statements using an output variation known as short-circuit syntax:
<?="This is another PHP example.";?>
This is functionally equivalent to both of the following variations:
<? echo "This is another PHP example."; ?>
<?php echo "This is another PHP example.";?>
