It's the very first entry: Array ( [0] => 9 [1] => 26 [2] => 31 ... } That's why array_rand is generating it. If you mean to generate values of $a rather than keys do: for ($i = 0; $i < 6; $i++) { if ($i) echo " - "; echo $a[$rand_keys[$i]]; } ------------------------------------------------------------------------ [2013-07-04 10:03:17] terracota09 at gmail dot com Description: ------------ http://localhost:8080/arrayAleatorio.php?juego=8 <?php // 2 primeros numeros = nº juegos; $a = array(9, 26, 31, 42, 4, 2, 11, 13, 19, 20, 23, 24, 28, 30, 39, 39, 1, 5, 14, 18, 36, 49, 15, 16, 25, 27, 33, 34, 38, 43, 48, 7, 10, 22, 32, 3, 6, 35, 44, 47, 8, 12, 17, 29, 37, 45, 21, 46, 40, 41); for ($j = 1; $j < $_GET["juego"]+1; $j++) { echo "<p style='font-family: Arial; font-size: 2em; text-align: center; color: blue'>"; $rand_keys = array_rand($a, 6); asort($rand_keys); print_r($rand_keys); //$i = 0; for ($i = 0; $i < 6; $i++) { //foreach ($rand_keys as $val) { //$i++; if ($i < 5) echo $rand_keys[$i]." - "; //echo $val." - "; else echo $rand_keys[$i]; //echo $val; } echo "</p>"; if (($j%2) == 0) echo "<br/>"; } Test script: --------------- Array ( [0] => 4 [1] => 8 [2] => 13 [3] => 16 [4] => 17 [5] => 46 ) 4 - 8 - 13 - 16 - 17 - 46 Array ( [0] => 7 [1] => 9 [2] => 11 [3] => 16 [4] => 28 [5] => 32 ) 7 - 9 - 11 - 16 - 28 - 32 Array ( [0] => 18 [1] => 23 [2] => 29 [3] => 34 [4] => 35 [5] => 43 ) 18 - 23 - 29 - 34 - 35 - 43 Array ( [0] => 1 [1] => 6 [2] => 7 [3] => 13 [4] => 27 [5] => 44 ) 1 - 6 - 7 - 13 - 27 - 44 Array ( [0] => 7 [1] => 14 [2] => 32 [3] => 41 [4] => 42 [5] => 48 ) 7 - 14 - 32 - 41 - 42 - 48 Array ( [0] => 7 [1] => 13 [2] => 15 [3] => 22 [4] => 27 [5] => 38 ) 7 - 13 - 15 - 22 - 27 - 38 Array ( [0] => 0 [1] => 2 [2] => 3 [3] => 29 [4] => 43 [5] => 49 ) 0 - 2 - 3 - 29 - 43 - 49 Array ( [0] => 18 [1] => 23 [2] => 33 [3] => 34 [4] => 36 [5] => 39 ) 18 - 23 - 33 - 34 - 36 - 39 Expected result: ---------------- 0 not exist in array Actual result: -------------- Array ( [0] => 4 [1] => 8 [2] => 13 [3] => 16 [4] => 17 [5] => 46 ) 4 - 8 - 13 - 16 - 17 - 46 Array ( [0] => 7 [1] => 9 [2] => 11 [3] => 16 [4] => 28 [5] => 32 ) 7 - 9 - 11 - 16 - 28 - 32 Array ( [0] => 18 [1] => 23 [2] => 29 [3] => 34 [4] => 35 [5] => 43 ) 18 - 23 - 29 - 34 - 35 - 43 Array ( [0] => 1 [1] => 6 [2] => 7 [3] => 13 [4] => 27 [5] => 44 ) 1 - 6 - 7 - 13 - 27 - 44 Array ( [0] => 7 [1] => 14 [2] => 32 [3] => 41 [4] => 42 [5] => 48 ) 7 - 14 - 32 - 41 - 42 - 48 Array ( [0] => 7 [1] => 13 [2] => 15 [3] => 22 [4] => 27 [5] => 38 ) 7 - 13 - 15 - 22 - 27 - 38 Array ( [0] => 40 [1] => 2 [2] => 3 [3] => 29 [4] => 43 [5] => 49 ) 40 - 2 - 3 - 29 - 43 - 49 Array ( [0] => 18 [1] => 23 [2] => 33 [3] => 34 [4] => 36 [5] => 39 ) 18 - 23 - 33 - 34 - 36 - 39 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65202&edit=1
