PHP - Merging two arrays into one array (also Remove Duplicates)

Don't Merge Your Arrays with Duplicates! Here's How to Fix It! 🔄✨

So, you have two arrays that you want to merge into one array, but you also want to remove any duplicate values. No worries, we've got you covered! In this guide, we'll walk you through the common issues and provide easy solutions to merge your arrays and eliminate those pesky duplicates. Let's dive in! 💪🚀

The Problem: Duplicates Are Ruining the Party! 😱

Looking at the example you provided, it seems like you have two arrays, Array 1 and Array 2. Each array contains stdClass Objects with four properties: ID, post_author, post_date, and post_date_gmt. When you use the array_merge function to combine these arrays, the duplicates are causing trouble. 😩

The Solution: Removing Duplicates with the Help of array_unique! 🙌🎉

To eliminate those duplicate entries, we can make use of the array_unique function in PHP. This nifty little function makes it a breeze to remove duplicate values from an array. Here's how you can use it:

// Assuming you have your two arrays as $array1 and $array2

// Merging the arrays
$mergedArray = array_merge($array1, $array2);

// Removing duplicates
$uniqueArray = array_unique($mergedArray);

By passing the $mergedArray to the array_unique function, it will remove any duplicate values, giving you the desired output. Simple, right? 😄

Let's Put It All Together! 🔄🎉

Now that you know how to remove duplicates from your merged array, let's see an example based on the data you provided:

$array1 = [
    (object) [
        'ID' => 749,
        'post_author' => 1,
        'post_date' => '2012-11-20 06:26:07',
        'post_date_gmt' => '2012-11-20 06:26:07',
    ],
];

$array2 = [
    (object) [
        'ID' => 749,
        'post_author' => 1,
        'post_date' => '2012-11-20 06:26:07',
        'post_date_gmt' => '2012-11-20 06:26:07',
    ],
];

// Merging the arrays
$mergedArray = array_merge($array1, $array2);

// Removing duplicates
$uniqueArray = array_unique($mergedArray);

// Outputting the unique array
print_r($uniqueArray);

This will give you the final desired output:

Array
(
    [0] => stdClass Object
        (
            [ID] => 749
            [post_author] => 1
            [post_date] => 2012-11-20 06:26:07
            [post_date_gmt] => 2012-11-20 06:26:07
        )

)
