将数组值转换为字符串 [英] converting array values to string

问题描述

    [a] => Array (
      [0] => MongoId Object (
        [$id] => 506479dc9a5be1596b1bd97d
      ),
      [1] => MongoId Object (
        [$id] => 506479dc9a5be1596b1bd97d
      )
    )

我有一个像这样的数组.我需要将值更改为字符串，以将其更改为如下所示:

I have an array like this one. I need to change the values to string, to change it to something like this:

array (
  0 => "506479dc9a5be1596b1bd97d",
  1 => "506479dc9a5be1596b1bd97d",
)

这是我的解决方案，但是它很昂贵，我将在for循环中使用它.

This is my solution, but it is expensive and I will be using this in a for loop.

$yut = implode(",", $a);
$arr = explode(",", $yut);

还有其他解决方法吗?

推荐答案

您可以只使用array_map调用 MongoId :: __ toString()会将数组中的所有Mongo对象转换为字符串

You can just use array_map to call MongoId::__toString() which would convert all Mongo Object in your array to string

$list = array_map(function($var){ return $var->__toString(); }, $yourArray);
