php - 将 MongoId 对象数组转换为字符串数组

Question

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

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，但它很昂贵，我将在 for 循环中使用它。

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

还有其他解决办法吗？

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

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