PHP array_push() Function

The PHP array_push() function is used to insert one or more elements to the end of an array. The function 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.

Note: To add an element to the array, it is better to use $array[] = because in this way there is no overhead of calling a function.

Syntax

array_push(array, value1, value2, ...)

Parameters

`array`	`Required.` Specify an array.
`value1, value2, ...`	`Optional.` Specify the values to push onto the end of the array.

Return Value

Returns the new number of elements in the array.

Exceptions

NA.

Example:

In the example below, array_push() function is used to add elements in the given array.

<?php
$Arr = array(10, 20);

//adding single element
array_push($Arr, 30);

//adding multiple elements
array_push($Arr, 40, 50);

print_r($Arr);
?>

The output of the above code will be:

Array
(
    [0] => 10
    [1] => 20
    [2] => 30
    [3] => 40
    [4] => 50
)

Example:

The example below shows the usage of array_push() function with an associative array.

<?php
$Arr = array("A"=>10, "B"=>20);

//add elements in the array
array_push($Arr, 30, 40);

print_r($Arr);
?>

The output of the above code will be:

Array
(
    [A] => 10
    [B] => 20
    [0] => 30
    [1] => 40
)
