可能重复：
Converting array and objects in array to pure array

我现在有一个数组，但它被传递给另一个将它转换为对象的函数，因为它需要是一个标准数组才能工作。我需要将以下对象数组转换为标准数组：

[files] => stdClass Object
        (
            [1] => stdClass Object
                (
                    [name] => price-my-insurance.jpg
                    [type] => image/jpeg
                    [tmp_name] => /Applications/MAMP/tmp/php/phpfmRfyN
                    [error] => 0
                    [size] => 911376
                )

            [2] => stdClass Object
                (
                    [name] => sideshows.jpg
                    [type] => image/jpeg
                    [tmp_name] => /Applications/MAMP/tmp/php/phpTamdHy
                    [error] => 0
                    [size] => 967656
                )

            [3] => stdClass Object
                (
                    [name] => the-beer-scale.jpg
                    [type] => image/jpeg
                    [tmp_name] => /Applications/MAMP/tmp/php/phpwCmwlW
                    [error] => 0
                    [size] => 742219
                )

            [4] => stdClass Object
                (
                    [name] => the-little-lace.jpg
                    [type] => image/jpeg
                    [tmp_name] => /Applications/MAMP/tmp/php/phpFnUuf8
                    [error] => 0
                    [size] => 939963
                )

            [5] => stdClass Object
                (
                    [name] => varrstoen-australia.jpg
                    [type] => image/jpeg
                    [tmp_name] => /Applications/MAMP/tmp/php/phpUtWyk1
                    [error] => 0
                    [size] => 2204400
                )

        )

到此：

Array
(
    [1] => Array
        (
            [name] => price-my-insurance.jpg
            [type] => image/jpeg
            [tmp_name] => /Applications/MAMP/tmp/php/phpfmRfyN
            [error] => 0
            [size] => 911376
        )

    [2] => Array
        (
            [name] => sideshows.jpg
            [type] => image/jpeg
            [tmp_name] => /Applications/MAMP/tmp/php/phpTamdHy
            [error] => 0
            [size] => 967656
        )

    [3] => Array
        (
            [name] => the-beer-scale.jpg
            [type] => image/jpeg
            [tmp_name] => /Applications/MAMP/tmp/php/phpwCmwlW
            [error] => 0
            [size] => 742219
        )

    [4] => Array
        (
            [name] => the-little-lace.jpg
            [type] => image/jpeg
            [tmp_name] => /Applications/MAMP/tmp/php/phpFnUuf8
            [error] => 0
            [size] => 939963
        )

    [5] => Array
        (
            [name] => varrstoen-australia.jpg
            [type] => image/jpeg
            [tmp_name] => /Applications/MAMP/tmp/php/phpUtWyk1
            [error] => 0
            [size] => 2204400
        )

)

我坚持使用foreach循环来执行此操作。

Here is a screenshot of the output

Answer 1

我会以懒惰的方式做到这一点：

$jsonstring = json_encode($theObj);
$array = json_decode($jsonstring,true);

Php Doc

<强> ASSOC
如果为TRUE，则返回的对象将转换为关联数组。

编辑：我刚测试过这个：

<?php
$o = new stdClass();
$o->property = "somepath";

$a = array($o,$o);
$js = json_encode($a);
$array = json_decode($js,true);
var_dump($array);
?>

这是输出：

array(2) {
  [0]=>
  array(1) {
    ["property"]=>
    string(8) "somepath"
  }
  [1]=>
  array(1) {
    ["property"]=>
    string(8) "somepath"
  }
}

Answer 2

$array = array();

foreach ($files as $k => $v) {
    if (!is_array($array[$k])) {
        $array[$k] = array();
    }

    foreach ($v as $j => $u) {
        $array[$k][$j] = $u;
    }
}

不完全确定它会起作用。可能更容易做出懒惰的json_decode(json_encode($obj),true)方式，就像@Ibu说的那样。
