PHP Tags¶
When PHP parses a file, it looks for opening and closing tags, which are <?php and ?> which tell PHP to start and stop interpreting the code between them.
The classic PHP tag is <?php
, and it also has a short version, for better serving xml tags : <?. This one relies on the short_open_tag
directive.
Previously, PHP supported also Javascript-style and ASP-style tags, though these are now unsupported.
<?php
// This is the classic PHP tag
?>
<?
// This is the short PHP tag
?><?= "Hello world";
// This is the short echo PHP tag
?>
