Is there a function to make a copy of a PHP array to another?

📝 The Ultimate Guide to Copying PHP Arrays 📝

Are you tired of getting burned when trying to copy PHP arrays? Do you find yourself struggling to copy an array defined inside an object to a global one outside of it? Look no further! In this guide, we will explore common issues and provide easy solutions for making a copy of a PHP array to another. Let's dive right in! 💪

Problem: Copying PHP Arrays

Have you ever encountered a scenario where you needed to create a copy of a PHP array? Perhaps you're working with an object and want to copy the array defined within it to a separate global array. This can be particularly tricky if you're not familiar with the right approach. But fear not, we've got you covered! 😉

Solution: The Array Copy Function

Luckily, PHP provides a built-in function called array_copy that allows us to make a copy of an array to another. Here's how you can use it:

$originalArray = array(1, 2, 3, 4, 5);
$newArray = array_copy($originalArray);

🔎 In this example, we create a copy of $originalArray and assign it to $newArray.

Alternative Solution: The Spread Operator (PHP 7.4+)

If you're using PHP 7.4 or later, you have another option available to you - the spread operator! This operator allows you to merge the elements of an array into another array. Here's how you can use it to create a copy of an array:

$originalArray = array(1, 2, 3, 4, 5);
$newArray = [...$originalArray];

🔎 In this example, the spread operator ... is used to merge the elements of $originalArray into the new array $newArray, effectively creating a copy.

Final Thoughts

Copying PHP arrays doesn't have to be a painful experience. By using the array_copy function or the spread operator available in PHP 7.4+, you can easily make copies of arrays without breaking a sweat. Remember to choose the solution that best suits your PHP version and coding style.
