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

Charles Iliya Krempeaux has a nice writeup on the issue and a function that worked really well for me:

function shuffle_assoc($array)
{
    // Initialize
        $shuffled_array = array();


    // Get array's keys and shuffle them.
        $shuffled_keys = array_keys($array);
        shuffle($shuffled_keys);


    // Create same array, but in shuffled order.
        foreach ( $shuffled_keys AS $shuffled_key ) {

            $shuffled_array[  $shuffled_key  ] = $array[  $shuffled_key  ];

        } // foreach


    // Return
        return $shuffled_array;
}
