array_splice — Remove a portion of the array and replace it with something else This function has 4 arguments: input - the array you want to splice, the offset - the key from where you want to remove. If your offset is 2(the array keys starts from 0 so 2 is the third not the second) that means it will start removing from the third element, the length - if the length is 4 and the offset is 2 it will remove starting from the third 4 elements. If the lenght is not specified it remove everything starting with the offset replacement - If replacement array is specified, then the removed elements are replaced with elements from this array.

$input = array("red", "green", "blue", "yellow");
array_splice($input, 2);
// $input is now array("red", "green")

$input = array("red", "green", "blue", "yellow");
array_splice($input, 1, -1);
// $input is now array("red", "yellow")

$input = array("red", "green", "blue", "yellow");
array_splice($input, -1, 1, array("black", "maroon"));

// $input is now array("red", "green", "blue", "black", "maroon")```
