What is the best way to sum variables on a page in PHP?

To sum variables on a page in PHP, you can create an array of the variables you want to sum and then use the array_sum() function to calculate the total sum. This approach allows for flexibility in adding or removing variables to be summed.

// Define variables to be summed
$var1 = 10;
$var2 = 20;
$var3 = 30;

// Create an array of variables
$variables = array($var1, $var2, $var3);

// Calculate the total sum
$totalSum = array_sum($variables);

// Output the total sum
echo "The total sum is: " . $totalSum;
