array_push

PHP function Edit on GitHub ✎

(PHP 4, PHP 5, PHP 7, PHP 8)

Push one or more elements onto the end of array

Description

array_push(array $array, mixed ...$values): int

array_push() treats array as a stack, and pushes the passed variables onto the end of array. The length of array increases by the number of variables pushed. Has the same effect as:

php

<?php
$array[] = $var;
?>

repeated for each passed value.

Note

If you use array_push() to add one element to the array, it's better to use $array[] = because in that way there is no overhead of calling a function.

Note

array_push() will raise a warning if the first argument is not an array. This differed from the $var[] behaviour where a new array was created, prior to PHP 7.1.0.

Parameters

array: The input array.
values: The values to push onto the end of the array.

Return Values

Returns the new number of elements in the array.
