In what ways can the use of array functions like array_map and array_filter improve the readability of PHP code, as mentioned in the forum?

Using array functions like array_map and array_filter can improve the readability of PHP code by providing a more concise and expressive way to manipulate arrays. These functions allow for cleaner and more readable code by removing the need for explicit loops and conditional statements. By using these functions, the code becomes more declarative and easier to understand for other developers.

// Example of using array_map to double the values of an array
$numbers = [1, 2, 3, 4, 5];
$doubledNumbers = array_map(function($num) {
    return $num * 2;
}, $numbers);

print_r($doubledNumbers);
