PHP在一维数组数组中转换多维数组

Question

I have array of 15 elements and each element contains 1000 arrays. How can I convert all this arrays in one simple dimensional array? I need to get this inner arrays and convert this in one dimensional array of arrays.

    Array
(
    [0] => Array
        (
            [0] => Array[0..999]
            [1] => Array[0..999]
            [2] => Array[0..999]
        )

    [1] => Array
        (
            [0] => Array[0..999]///items are also arrays
            [1] => Array[0..999]
        )

    [2] => Array
        (

            [0] => Array[0..999]
            [1] => Array[0..999]
            [2] => Array[0..999]
        )
....

It needs to look like this:

 Array(
[0] => Array
    [0]=>value
    [1]=>value
    [2]=>value

[1] => Array
    [0]=>value
    [1]=>value
    [2]=>value
)

Answer 1

array_merge() will merge multiple arrays, but you have an unspecified number in the main array. So use the array as the parameters for call_user_func_array() with array_merge() as the callback:

$result = call_user_func_array('array_merge', $array);
