Inserting values anywhere in the PHP array

Array_splice ()

$arr = Array (' A ', ' B ', ' C ');

$arr 2 = ' abc ';
$t = Array_splice ($arr, 1, 0, $arr 2);

Print_r ($arr);

Console output:

Array ([0] = ' A ' [1] = ' abc ' [2] = ' B ' [3] = ' C ');

A brief introduction to the Array_splice method, parameter one is an array of operations, parameter two is the index value of the operation element, parameter three is the length, parameter four is to replace the element.

The effect of this method is to delete the coherent element with 1 as the starting position, length 0 in $arr, and then fill it with $ARR2.

Tips: If the length is 0, then the effect is equivalent to inserting the specified element at the specified index value.
