How to push both value and key into PHP array

How to Push Both Value and Key into PHP Array 🚀

Are you struggling to push both the value and key into a PHP array? 😫 Don't worry, I've got you covered! In this guide, I'll walk you through a common issue faced by many developers and provide easy solutions to achieve the desired result. By the end, you'll be able to effortlessly push both the value and key into your PHP array. Let's get started, shall we? 💪

The Problem

Let's first understand the context around this question with a piece of code:

$GET = array();    
$key = 'one=1';
$rule = explode('=', $key);
/* array_push($GET, $rule[0] => $rule[1]); */

The code snippet above shows an attempt to push both the key and value into the $GET array. However, using the array_push function in this way won't work. 😞

The Solution

To achieve the desired output ($GET[one => 1, two => 2, ...]), we need to use a different approach. Fortunately, PHP provides us with a handy function called array_combine that does exactly what we need. 🎉

Here's how you can solve the problem using array_combine:

$GET = array();
$key = 'one=1';
$rule = explode('=', $key);
$GET = array_combine([$rule[0]], [$rule[1]]);

In the code above, we first initialize the $GET array. Next, we explode the $key string using the = delimiter to separate the key and value. Finally, we use array_combine to combine the key and value arrays into a single associative array.

Explanation

Let's break down the solution step by step:

1. Initialize the $GET array:

$GET = array();

1. Explode the $key string into an array:

$key = 'one=1';
$rule = explode('=', $key);

After this step, the $rule array will contain the key and value respectively, i.e., $rule[0] => 'one' and $rule[1] => 1.

1. Use array_combine to combine the key and value arrays:

$GET = array_combine([$rule[0]], [$rule[1]]);

By passing an array containing the key ($rule[0]) and an array containing the value ($rule[1]) to array_combine, we create the final associative array where the key ($rule[0]) points to the value ($rule[1]).

And that's it! You have successfully pushed both the value and key into the PHP array using array_combine. 🎉

Better Approach: Associative Array Initialization

Alternatively, you can also initialize the $GET array with the key and value directly, eliminating the need for array_combine. Here's how:

$GET = array(
    $rule[0] => $rule[1]
);

By assigning the key and value directly in the array initialization, you achieve the same result without using array_combine.

Conclusion

Pushing both the value and key into a PHP array may seem daunting at first, but with the help of array_combine or direct initialization, you can tackle it effortlessly. 🙌

Now that you have learned the solutions, it's time to apply them in your own code. Give it a try and see the magic happen! 💫
