在PHP阵列产生随机数

Question

我有以下代码：

<?php 

function randomGen($min, $max, $quantity) { 
    $numbers = range($min, $max); 
    shuffle($numbers); 
    return array_slice($numbers, 0, $quantity); 
} 




for ($row = 0; $row < 5; $row++) { 
    echo "<p><b>Set: $row</b></p>"; 

print_r(randomGen(1,36,6)); 
} 
//}//} 
?> 

其例如输出：

Set: 0 
Array ([0] => 32 [1] => 35 [2] => 22 [3] => 29 [4] => 8 [5] => 17) 
Set: 1 
Array ([0] => 25 [1] => 28 [2] => 8 [3] => 30 [4] => 13 [5] => 9) 
Set: 2 
Array ([0] => 24 [1] => 31 [2] => 33 [3] => 28 [4] => 2 [5] => 32) 
Set: 3 
Array ([0] => 1 [1] => 6 [2] => 33 [3] => 2 [4] => 14 [5] => 29) 
Set: 4 
Array ([0] => 17 [1] => 25 [2] => 6 [3] => 15 [4] => 24 [5] => 22) 

但是我想为结果显示为：只的数量，实施例：

32 35 22 29 8 17 

ETC，我怎么能去删除它们

请勿使用print_r() - 此功能也固有地打印索引。

$array = randomGen(1,36,6); 
foreach($array as $key => $val){ 
    echo $val; 
} 

$key是你不想要的索引;我将其列入教育目的。

$array = randomGen(1,36,6); 
foreach($array as $val){ 
    echo $val; 
}
