array_push — Push one or more elements onto the end of array

Description ¶

int array_push ( array &$array , mixed $value1 [, mixed $... ] )

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

$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 differs from the $var[] behaviour where a new array is created.

Parameters ¶

array

The input array.

value1

The first value to push onto the end of the array.

Return Values ¶

Returns the new number of elements in the array.

Examples ¶

Example #1 array_push() example

<?php

$stack = array("orange", "banana");

array_push($stack, "apple", "raspberry");

print_r($stack);

?>

The above example will output:

Array

(

    [0] => orange

    [1] => banana

    [2] => apple

    [3] => raspberry

)
