How to Merge Two Array in PHP?

Hello Developer,

In this article, we'll explore how to merge two arrays in PHP, covering the use of the array_merge() function and the union operator (+). This guide will help you understand the differences and applications of each method when combining arrays in PHP, whether you're working in a Laravel environment or a plain PHP setup. We will look at how to append two arrays together and merge multiple arrays, with practical examples to illustrate each approach.

We'll use the array_merge() function and the + operator to demonstrate merging multiple arrays. Let's delve into the examples:

Example 1: Using array_merge()

<?php
  
    $arrayOne = ["One", "Two", "Three"];
    $arrayTwo = ["Four", "Five"];
        
    $newArray = array_merge($arrayOne, $arrayTwo);
    
    var_dump($newArray);
  
?>

Output:

array(5) {
  [0]=> string(3) "One"
  [1]=> string(3) "Two"
  [2]=> string(5) "Three"
  [3]=> string(4) "Four"
  [4]=> string(4) "Five"
}

Example 2: Using the + Operator

<?php
  
    $arrayOne = [1 => "One", 2 => "Two", 3 => "Three"];
    $arrayTwo = [4 => "Four", 5 => "Five"];
        
    $newArray = $arrayOne + $arrayTwo;
    
    var_dump($newArray);
  
?>

Output:

array(5) {
  [1]=> string(3) "One"
  [2]=> string(3) "Two"
  [3]=> string(5) "Three"
  [4]=> string(4) "Four"
  [5]=> string(4) "Five"
}

This tutorial should help you effectively merge arrays in PHP, catering to different requirements and ensuring data integrity when combining array elements.
