How to Add Items to Array in php

In php, we can add items to arrays easily. If you want to add items to the end of an array, you can use the php array_push() function.

$example = array("lion");

array_push($example, "bear", "snake", "horse");

print_r($example);

//Output:
Array
(
    [0] => lion
    [1] => bear
    [2] => snake
    [3] => horse
)

If you want to add items at the beginning of an array, you can use the php array_unshift() function.

$example = array("lion");

array_unshift($example, "bear", "snake", "horse");

print_r($example);

//Output:
Array
(
    [0] => bear
    [1] => snake
    [2] => horse
    [3] => lion
)
