How can using arrays in PHP simplify the process of selecting and summing the largest variables in an array?

When selecting and summing the largest variables in an array, using arrays in PHP can simplify the process by allowing you to easily iterate through the array, compare values, and sum the largest variables. By storing the values in an array, you can use built-in PHP functions like max() to find the largest value, and array_sum() to calculate the sum of the largest variables. 

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

// Find the largest value in the array
$largest = max($values);

// Sum all values greater than or equal to the largest value
$sum = array_sum(array_filter($values, function($value) use ($largest) {
    return $value >= $largest;
}));

echo $sum; // Output: 120
