如何更改php数组的结构

Question

I have an array but the structure isnt good so I wanted it to change.

The array is an array with arrays in it, but 1 is always empty so I dont need this one, and therefor there's no need for a multilevel array.

Current array

array(

    [0] => array( 
        [0] => some value
        [1] => some value
    ),
    [1] => array( empty so this one must be removed )

)

The way that I want it to be

array( 
        [0] => some value
        [1] => some value
    )

Answer 1

You can use like below.

array_reduce($array, 'array_merge', array());

For Example:

$a = array(array(1, 2, 3), array(4, 5, 6));
$result = array_reduce($a, 'array_merge', array());

Result:

array[1, 2, 3, 4, 5, 6];
