在PHP中随机选择一个数组 [英] Randomly picking out of an array in PHP

问题描述

我有一个数组，其值类似于1、5、6、9、11、45、56等.我试图做的是随机分配一个值，也许是6.然后我想选择一个随机值值不包括6(因此不能加倍).然后是一个随机值，不包括最后两个，全部来自数组内部.有什么帮助吗?我正在尝试不使用while循环来执行此操作，但是如果有必要，那就这样吧.

I have an array that has values like 1, 5, 6, 9, 11, 45, 56, etc. What I'm trying to do is to randomly one value, perhaps 6. Then I want to pick a random value excluding 6 (so no doubles). Then a random value excluding the last two, all from inside an array. Any help? I'm trying to do this without while loops but if they are necessary then so be it.

推荐答案

我建议以下内容:

# pick a random key in your array
$rand_key = array_rand($your_array);

# extract the corresponding value
$rand_value = $your_array[$rand_key];

# remove the key-value pair from the array
unset($your_array[$rand_key]);
