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);

?>

The example works great.

Here is the output.

array(3) {
  [0]=>
  string(5) "apple"
  [1]=>
  string(7) "banana "
  [2]=>
  string(11) " cranberry "
}
array(3) {
  [0]=>
  string(5) "apple"
  [1]=>
  string(6) "banana"
  [2]=>
  string(9) "cranberry"
}

Notice the different lengths for banana and cranberry.
