在 PHP 中生成 z 和 y 范围内的随机 x 数

Question

有没有办法在 php 中的数字 24 - 51 之间的数组中生成 65 个随机数。这只是我正在尝试做的一个例子。我一直在寻找两个数字的范围或选择一个数字但没有生成 65 个数字，这将在一系列数字之间重复。

Answer 1

要在数字 24 - 51 之间的数组中生成 65 个随机数，您可以使用 for loop and mt_rand 函数。

$arr = [];
$n = 65;
$r_min = 24;
$r_max = 51;
for ($i = 1; $i <= $n; $i++) {
    $arr[] = mt_rand($r_min, $r_max);
}
print_r($arr);

将打印例如：（输出当然每次都会改变）
