Description:
------------
The second example's output at http://docs.php.net/wincache_ucache_add is not correct.

Reproduce code:
---------------
<?php
	$colors_array = array('green' => '5', 'Blue' => '6', 'yellow' => '7', 'cyan' => '8');
	var_dump(wincache_ucache_add($colors_array));
	var_dump(wincache_ucache_add($colors_array));
	var_dump(wincache_ucache_get('Blue'));
?>

Expected result:
----------------
array(0) { } array(4) { ["green"]=> int(-1) ["Blue"]=> int(-1) ["yellow"]=> int(-1) ["cyan"]=> int(-1) } string(1) "6" 

Actual result:
--------------
array(0) {}
bool(false)
string(1) "6"
