PHP Random Shuffle Array Maintaining Key => Value

Question

I\'ve been looking on google for the answer but can\'t seem to find something fool-proof and cant really afford to mess this up (going live into a production site).

Answer 1

I was having a hard time with most of the answers provided - so I created this little snippet that took my arrays and randomized them while maintaining their keys:

function assoc_array_shuffle($array)
{
    $orig = array_flip($array);
    shuffle($array);
    foreach($array AS $key=>$n)
    {
        $data[$n] = $orig[$n];
    }
    return array_flip($data);
}
