Commenting in PHP is simple and effective.

Writing notes to yourself, within your code, is the only way to keep track of a large file. Coming back to an uncommented 300-line page of code can be a nightmare.

To insert a single line comment within php code type // before the line. To insert a multi-line comment within code start the comment with /* and end it with */. For example:

<?php

$example = 1

//this is a comment that will be ignored. But will help me remember what the code means.

if (!randomfunction($_POST[dart])){function(example); $example ++;}


/*This is a long
multi-line comment that will
help me remember what the code means.
It will be ignored by the php-
parser*/

randomfuction($example);
?>
