Description:
------------
When comparing 2 arrays in an if statement, array equality according to the 
documentation (http://www.php.net/manual/en/language.operators.array.php) does not 
work. According to the docs, order should not matter, but when comparing 2 arrays 
directly it does.

Test script:
---------------
<?php

// based off of http://www.php.net/manual/en/language.operators.array.php

$a = array("apple", "banana");
$b = array(1 => "banana", "0" => "apple");


## WORKS ##
var_dump($a == $b); // bool(true)
var_dump($a === $b); // bool(false)
var_dump(array("apple", "banana") == array(1 => "banana", "0" => "apple")); // bool(true)


## FAILS? ##
if (array('apple','banana') == array(1 => 'banana',2=>'apple'))
   echo "they are equal.\n";
else
   echo "They are not equal.\n"; // this is the response I get

## yet if I do:
if ($a == $b)
   echo "they are equal.\n"; // this is the response I get...
else 
   echo "They are not equal.\n";



?>

Expected result:
----------------
bool(true)
bool(false)
bool(true)
they are equal.
they are equal.

Actual result:
--------------
bool(true)
bool(false)
bool(true)
They are not equal.
they are equal.
