如何在PHP循环中的数组内部循环 [英] How to loop inside an array inside a loop in PHP

问题描述

基本上，我想做的是在一个循环内和数组中循环.我不知道该怎么做(这就是为什么我在这里)，并且我一直在测试很多东西.

Basically, what I'm trying to do is loop inside a loop and in arrays. I have no idea how to do it (that's why I'm here) and I've been testing many things.

听起来很困惑，我写下了代码的样子，但是显然那是不正确的.

As it sounds very confused I write down the code how it would be, but clearly that's not correct.

这是我尝试过的.

This below is what I've tried.

$whatever->insertOne(
    ['name' => 'whatever',
    'data' => array(
        for ($i = 0 ; $i < 50 ; $i++) { // <-first loop
            'something' => array(
                for ($j = 0 ; $j < 50 ; $j++) { // <-second loop
                    'somevalue' => array(
                        'date' => $date,
                        'value' => mt_rand(0,200)
                    ) 
                }
            )
        }
    )

    ]);

推荐答案

循环需要在外部才能创建最终数组.不要在数组内添加循环.

Loop need to be outside to create final array. Don't add loop inside an array.

您可能需要类似以下的内容:-

You probably need something like below:-

$data = ['name' => 'whatever'];

for ($i = 0 ; $i < 50 ; $i++) {
  for ($j = 0 ; $j < 50 ; $j++) {
    $data[$i]['something'][$j]=['somevalue' => array('date' => $date,'value' => mt_rand(0,200));
  }
}

$whatever->insertOne($data);

注意: -您可以在insertOne()之前打印数组，以检查是否获得了正确格式的数组或需要更多操作的数组.谢谢

Note:- you can print your array before insertOne() to check that you are getting array of correct format or some more manipulation needed.Thanks
