<?php
/**
* Similar to the php foreach block, loops over an array
*
* Note that if you don't provide the item parameter, the key will act as item
* <pre>
* * from : the array that you want to iterate over
* * key : variable name for the key (or for the item if item is not defined)
* * item : variable name for each item
* * name : foreach name to access it's iterator variables through {$.foreach.name.var} see {@link http://wiki.dwoo.org/index.php/IteratorVariables} for details
* </pre>
* Example :
*
* <code>
* {foreach $array val}
* {$val.something}
* {/foreach}
* </code>
