Introduction

I use this almost every day. It's one of the most useful PHP debugging tools. You can print all of the contents of a variable (class, array or scalar) to get an idea of how the structure looks.

Grab the Code

<?php
    print "<pre>";
    print_r($variable);
    print "</pre>";
?>

Has a purpose, but that is about it.

another way of doing this is with printf();
Code:
printf('<pre>%s</pre>', print_r($variable, true));
