var dump in php code example

Example: var_dump php

dumping objects that reference each other could lead to infinite recursion
<?php 
$brother = new Sibling();
$sister = new Sibling();
$brother->sister = $sister;
$sister->brother = $brother;

var_dump($brother); 
/* dumps all of $brother's properties, including "sister", which dumps all of $sister's properties, including "brother", etc. */
?>
