Are there any best practices for efficiently working with arrays in PHP?

When working with arrays in PHP, it is important to use built-in array functions efficiently to manipulate and iterate through arrays. Avoid using nested loops whenever possible, as they can lead to performance issues with large arrays. Instead, utilize functions like array_map, array_filter, and array_reduce to perform operations on arrays in a more concise and efficient manner.

// Example of efficiently working with arrays using array_map
$numbers = [1, 2, 3, 4, 5];

// Double each number in the array
$doubledNumbers = array_map(function($num) {
    return $num * 2;
}, $numbers);

print_r($doubledNumbers);
