Array merge recursive static random

Question

Update : I've write my functions, and it works.

My Own Answer

<?php
function array_merge_recursive_random_static($first_array, $second_array, $key='')
{
    $merged_array = array_merge_recursive($first_array, $second_array);
    $arrays = &$merged_array;
    mt_srand(strlen($key)); 
    for ($i = count($arrays) - 1; $i > 0; $i--)
    { 
        $j = @mt_rand(0, $i); 
        $tmp = $arrays[$i]; 
        $arrays[$i] = $arrays[$j]; 
        $arrays[$j] = $tmp; 
    }
    return $arrays;
}
?>

My Own Question :

I have two arrays like this:

$array2 = array(
          0 => array('id' => 'dada', 'title' => 'this dada', 'desc' => 'dadaeating'),
          1 => array('id' => 'caca', 'title' => 'this caca', 'desc'=> 'caca eating') 
);

$array2 = array(
          0 => array('id' => 'baba', 'title' => 'this baba', 'desc' => 'baba eating'),
          1 => array('id' => 'memo', 'title' => 'this memo', 'desc'=> 'memo eating') 
);

I want merge $array1 and $array2 and make it static random unique, so I want my result like this :

$arrays = array(
          0 => array('id' => 'caca', 'title' => 'this caca', 'desc' => 'cacaeating'),
          2 => array('id' => 'memo', 'title' => 'this memo', 'desc'=> 'memo eating'),
          3 => array('id' => 'dada', 'title' => 'this dada', 'desc'=> 'dada eating'),
          4 => array('id' => 'baba', 'title' => 'this baba', 'desc'=> 'baba eating')
);

Everytime I reload page, output result always like result above.

I've found my answer :) yeah static random its useful for SEO, thanks — oknoorap

Just merge the arrays, then shuffle the resulting array.

$rand = array_merge($array1, $array2);
shuffle($rand);

$rand now contains the final version.
