Нещо, което разбърква масив ?

[bama]

Търся функция, която да разбърка даден масив. Пробвах array_rand, shuffle, но и при двете функции някои от елементите се повтарят..

shuffle(shuffle($array))?

Иначе това е функцията, която ти трябва.

Дава ми някаква грешка, която не знам как да оправя..
Warning: shuffle() expects parameter 1 to be array, boolean given in index.php on line 24
Ето кода

$cards = array("
k_A_1","k_2_2","k_3_3","k_4_4","k_5_5","k_6_6","k_7_7","k_8_8","k_9_9","k_10_10","k_11_11","k_12_12","k_13_13",
"s_A_1","s_2_2","s_3_3","s_4_4","s_5_5","s_6_6","s_7_7","s_8_8","s_9_9","s_10_10","s_11_11","s_12_12","s_13_13",
"u_A_1","u_2_2","u_3_3","u_4_4","u_5_5","u_6_6","u_7_7","u_8_8","u_9_9","u_10_10","u_11_11","u_12_12","u_13_13",
"p_A_1","p_2_2","p_3_3","p_4_4","p_5_5","p_6_6","p_7_7","p_8_8","p_9_9","p_10_10","p_11_11","p_12_12","p_13_13"
);
for($i = 1; $i <= 52; $i++){
$r_cards = shuffle(shuffle($cards));
$all_random_cards = $i."-".$cards[$r_cards]."|<br />";
print $all_random_cards;
}

червеното е грешният ред.
