Are there any specific PHP functions or libraries that could simplify the process of calculating averages in this scenario?

To simplify the process of calculating averages in PHP, you can use the `array_sum()` function to sum up all the values in an array and then divide by the number of elements in the array to calculate the average.

// Sample array of numbers
$numbers = [10, 20, 30, 40, 50];

// Calculate the average
$average = array_sum($numbers) / count($numbers);

// Output the average
echo "The average is: " . $average;
