如何在PHP中将二维数组转换为一维数组？

Question

我有一个多维数组得到如下给出的结果

Array
(
    [0] => Array
        (
            [0] => 70
        )

    [1] => Array
        (
            [0] => 67
        )

    [2] => Array
        (
            [0] => 75
            [1] => 73
            [2] => 68
        )

    [3] => Array
        (
            [0] => 68
        )

    [4] => Array
        (
            [0] => 76
        )

)

但我需要将其转换为单个数组

我想转换为单维数组

Array
(
[0] => 70
[1] => 67
[2] => 75
[3] => 73
[4] => 68
[5] => 68
[6] => 76
)

如何使用PHP函数转换它？

或者还有其他办法吗？

你可以试试

$it =  new RecursiveIteratorIterator(new RecursiveArrayIterator($data));
$l = iterator_to_array($it, false);

var_dump($l); // one Dimensional
