What are some best practices for optimizing array sum calculations in PHP to improve efficiency and performance?

When optimizing array sum calculations in PHP for efficiency and performance, it is recommended to use built-in functions like array_sum() instead of manually iterating over the array elements. This can significantly reduce the complexity and improve the speed of the calculation. 

// Using array_sum() function to optimize array sum calculations
$array = [1, 2, 3, 4, 5];

// Calculate sum using array_sum()
$sum = array_sum($array);

echo $sum; // Output: 15
