PHP Tutorial From beginner to master

PHP Syntax  
PHP code is executed on the server, and the plain HTML result is sent to the browser.  
Basic  PHP Syntax 
A PHP scripting block always starts with <?php   and ends with  ?> . A PHP scripting block can 
be placed anywhere in the document. 
On servers with shorthand support enabled you can start a scripting block with <? and end 
with ?>. 

For maximum compatibility, we recommend that you use the standard form (<?php) rather 
than the shorthand form.
