PHP Syntax

PHP scripting tag always starts with <?php and ends with ?>. PHP scripting tag can be use anywhere in the document.

There are four sets of tags which can be used to denote blocks of PHP code. Of these, only two (<?php. . .?> and <script language=”php”>. . .</script>) are always available; the others can be turned on or off from the php.ini configuration file. While the short-form tags and ASP-style tags may be convenient, they are not as portable as the longer versions.
