Are there any best practices for efficiently calculating the sum of an array in PHP?

To efficiently calculate the sum of an array in PHP, you can use the array_sum() function which calculates the sum of values in an array. This function is a built-in PHP function that can handle both integer and float values in the array. By using array_sum(), you can avoid writing a loop to iterate through the array and calculate the sum manually.

// Example array
$numbers = [1, 2, 3, 4, 5];

// Calculate the sum of the array
$sum = array_sum($numbers);

// Output the sum
echo "The sum of the array is: " . $sum;
