What are the advantages and disadvantages of using array functions versus loops for array manipulation in PHP?

When manipulating arrays in PHP, using array functions like `array_map`, `array_filter`, and `array_reduce` can often result in cleaner and more concise code compared to using loops. However, array functions may be less intuitive for beginners and can sometimes be less efficient than manually written loops, especially for complex operations.

// Example of using array functions for array manipulation
$numbers = [1, 2, 3, 4, 5];

// Using array_map to double each number
$doubledNumbers = array_map(function($num) {
    return $num * 2;
}, $numbers);

print_r($doubledNumbers);
