In terms of performance, when should array functions be preferred over loops for tasks like finding multiples in PHP?

When dealing with tasks like finding multiples in PHP, array functions should be preferred over loops for better performance. Array functions are optimized for handling arrays efficiently and can often perform operations on large datasets much faster than manually looping through each element. This can lead to significant performance improvements, especially when working with large arrays or complex data structures.

// Using array_filter to find multiples of 5 in an array
$numbers = [1, 5, 10, 15, 20, 25];
$multiplesOf5 = array_filter($numbers, function($num) {
    return $num % 5 == 0;
});

print_r($multiplesOf5);
