How to Sort a Multi-dimensional Array by Value

How to Sort a Multi-dimensional Array by Value 💪🔢

So you've got this multi-dimensional array and you need to sort it by the value of the "order" key, huh? No worries, I got you covered! 🙌

Let's break down the problem and find the easiest solution to make your life a breeze! 😎

The Problem 😰

The array you've shared looks something like this:

Array
(
    [0] => Array
        (
            [hashtag] => a7e87329b5eab8578f4f1098a152d6f4
            [title] => Flower
            [order] => 3
        )

    [1] => Array
        (
            [hashtag] => b24ce0cd392a5b0b8dedc66c25213594
            [title] => Free
            [order] => 2
        )

    [2] => Array
        (
            [hashtag] => e7d31fc0602fb2ede144d18cdffd816b
            [title] => Ready
            [order] => 1
        )
)

And you want to sort it in ascending order based on the "order" value. Seems tricky, but fear not! Here's a simple solution for you! 🤓

The Solution 🚀

To sort this multi-dimensional array by the value of the "order" key, you can use the usort() function in PHP. This function allows you to define a custom comparison function and sort the array based on your specific criteria.

Here's an example of how you can achieve this:

usort($array, function($a, $b) {
    return $a['order'] <=> $b['order'];
});

In this example, the usort() function takes two arguments: the array you want to sort ($array), and an anonymous function that defines the comparison logic. The function compares the "order" value of each array element using the spaceship operator (<=>), which returns -1, 0, or 1 depending on the values being compared.

After running this code, your array will be sorted in ascending order based on the "order" value. 🎉

The Call-to-Action 📢

Sorting a multi-dimensional array by value doesn't have to be a headache anymore! With the simple solution provided above, you can easily sort your arrays like a pro. Give it a try and see the magic happen! 😉
