Processing Instructions

A processing instruction is a method for passing information to applications that may read the document. It may also include the program or script itself. Unlike comments, which are intended for humans, processing instructions are for computer programs or scripts. Processing instructions are indicated by <? at the beginning and ?> at the end of the instruction.

The example document includes a processing instruction for a simple PHP command that displays the current date.

<?php print date('Fj, Y'); ?>
