How can the use of array_map and array_filter functions improve the readability and efficiency of the PHP code in this context?

Using array_map and array_filter functions can improve the readability and efficiency of PHP code by allowing for concise and clear transformations and filtering of arrays. These functions provide a more functional programming approach, making the code easier to understand and maintain. By utilizing these functions, we can avoid nested loops and conditional statements, resulting in cleaner and more efficient code.

// Original code without using array_map and array_filter
$numbers = [1, 2, 3, 4, 5];
$filteredNumbers = [];
foreach ($numbers as $number) {
    if ($number % 2 == 0) {
        $filteredNumbers[] = $number * 2;
    }
}

// Improved code using array_map and array_filter
$numbers = [1, 2, 3, 4, 5];
$filteredNumbers = array_filter($numbers, function($number) {
    return $number % 2 == 0;
});
$transformedNumbers = array_map(function($number) {
    return $number * 2;
}, $filteredNumbers);
