I don't think this is a duplicate, but maybe I'm just not using good keywords. I need to take a 2D array and add in another 2D array such that
$arr = array(array(1,2), array(3,4), array(7,8));
$arr2 = array(array(5,6));
array_splice($arr, ?, ?, $arr2);
Would give me back
[0] => 1,2
[1] => 3,4
[2] => 5,6
[3] => 7,8
I'm at a loss at how to do this, as the documentation isn't clear how to not remove any of the array but still add to it.
Thanks.
If you really want to use array_splice(), then you want to insert at position 2 and use an offset of 0 (neither positive nor negative) so you don't remove any existing values but move them up in position:
$arr = array(array(1,2), array(3,4), array(7,8));
$arr2 = array(array(5,6));
array_splice($arr, 2, 0, $arr2);
Use array_merge
<?php
$arr = array(array(1,2), array(3,4), array(7,8));
$arr2 = array(array(5,6));
$result = array_merge($arr, $arr2);
print_r($result);
Output:
Array
(
[0] => Array
(
[0] => 1
[1] => 2
)
[1] => Array
(
[0] => 3
[1] => 4
)
[2] => Array
(
[0] => 7
[1] => 8
)
[3] => Array
(
[0] => 5
[1] => 6
)
)
Array Merge Will do this for you.

array_splice() is use for remove elements from an array and replace it with new elements.
$arr2.
