Merge array into another array

Question

I need to merge an associative array into another associative array. I know php's array_merge but it returns a new array. That's not what I want.

Eg

$ar1 = array('one'=>1, 'two'=>2, 'three'=>3);
$ar2 = array('four'=>4, 'five'=>5);

I want to know that is there a php function which I can use to merge $ar2 into $ar1. The result should be,

$ar1 = array('one'=>1, 'two'=>2, 'three'=>3, 'four'=>4, 'five'=>5);

Can't you just use `array_merge` like this then: `$ar1 = array_merge($ar1, $ar2);` — Cyclonecode, Nov 24 '12 at 05:56
Without using array_merge you'd have to write a loop that combines them manually. Why can't you have a new array? — Sterling Archer, Nov 24 '12 at 05:58

$ar1 = array('one'=>1, 'two'=>2, 'three'=>3);
$ar2 = array('four'=>4, 'five'=>5);

use array_merge

$array3 = array_merge($ar1,$ar2);

it will merge the 2 array and store it in $array3. You can use $ar1 also.

The easiest way is to assign output of array_merge to your first array. Is this you want

<?php
$ar1 = array('one'=>1, 'two'=>2, 'three'=>3);
$ar2 = array('four'=>4, 'five'=>5);

$ar1 = array_merge($ar1,$ar2);

print_r($ar1);
?>
