The array_merge Function

The array_merge function merges two or more arrays together. If the arrays being merged contain the same keys - only one such element will remain. If you need to keep all elements with the same keys - use the function array_merge_recursive.

Syntax

phparray_merge(array ...$arrays): array

Example

Let's merge two arrays together:

php<?php
  $arr1 = ['a', 'b', 'c', 'd', 'e'];
  $arr2 = [1, 2, 3, 4, 5];
  
  $res = array_merge($arr1, $arr2);
  var_dump($res);
?>

Code execution result:

php['a', 'b', 'c', 'd', 'e', 1, 2, 3, 4, 5]

Example

Let's merge three arrays together:

php<?php
  $arr1 = [1, 2, 3];
  $arr2 = [4, 5, 6];
  $arr3 = [7, 8, 9];
  
  $res = array_merge($arr1, $arr2, $arr3);
  var_dump($res);
?>

Code execution result:

php[1, 2, 3, 4, 5, 6, 7, 8, 9]
