Description:
------------
Example 2466 on the "trim" explanation page makes no sense, function "trim_value" isn't called anywhere, instead it uses "var_dump" from the example on top of it:

<?php
function trim_value(&$value)
{
    $value = trim($value);
}

$fruit = array('apple','banana ', ' cranberry ');
var_dump($fruit);

array_walk($fruit, 'trim_value');
var_dump($fruit);

?>
