Calculating Sum of Values in a Foreach Loop in PHP

In the given code snippet, you have a foreach loop that iterates through the elements of the $group array and prints the key and value of each element. However, you want to calculate the sum of the values in the $group array.

To achieve this, you can declare a variable $sum and initialize it to 0 before the foreach loop. Inside the loop, you can add the current value to the $sum variable using the = operator. After the loop, you can echo the value of $sum to display the total sum of the values in the array.

Here's the updated code:

$sum = 0;
foreach($group as $key => $value)
{
    $sum  = $value;
}
echo $sum;

This code snippet initializes $sum to 0, then iterates through the elements of the $group array. For each element, it adds the value to the $sum variable. After the loop, it echoes the value of $sum, which is the sum of all the values in the array.
