Description:
------------
you have a wrong example in french documentation for  
function.array-search
In french you writte :
<?php
$array = array(0 => "bleu", 1 => "rouge", 2 => "vert", 3 => 
"rouge");

$key = array_search($array, "vert");? ? // $key = 2;
$key = array_search($array, "rouge");? // $key = 1;
?> 

It's right in english
<?php
$array = array(0 => 'blue', 1 => 'red', 2 => 'green', 3 => 
'red');

$key = array_search('green', $array); // $key = 2;
$key = array_search('red', $array);? // $key = 1;
?>
