What are the best practices for simplifying code readability when working with arrays in PHP?

When working with arrays in PHP, it is important to simplify code readability by using built-in array functions and avoiding complex nested loops. One way to achieve this is by breaking down complex operations into smaller, more manageable steps using functions like array_map, array_filter, and array_reduce. Additionally, using meaningful variable names and comments can also improve code readability. 

// Example of simplifying code readability when working with arrays in PHP
// Original code
$numbers = [1, 2, 3, 4, 5];
$result = [];
foreach ($numbers as $number) {
    if ($number % 2 == 0) {
        $result[] = $number * 2;
    }
}

// Simplified code
$numbers = [1, 2, 3, 4, 5];
$result = array_filter(array_map(function($number) {
    return $number * 2;
}, $numbers), function($number) {
    return $number % 2 == 0;
});
