In what situations would it be more beneficial to use array functions like array_sum() and count() for calculating averages in PHP?

When calculating averages in PHP, using array functions like array_sum() and count() would be more beneficial when dealing with arrays of numerical values. These functions provide a simple and efficient way to calculate the sum of the values in an array and count the number of elements in the array, which are essential for computing the average. By using these array functions, you can avoid manually iterating through the array to calculate the sum and count, making your code more concise and readable.

// Example of calculating average using array functions
$values = [10, 20, 30, 40, 50];

$sum = array_sum($values);
$count = count($values);

$average = $sum / $count;

echo "Average: " . $average;
