In what ways can PHP be optimized for efficiently handling mathematical tasks in a web application, especially when dealing with a large number of users?

To optimize PHP for efficiently handling mathematical tasks in a web application, especially with a large number of users, you can utilize built-in math functions, cache results to avoid redundant calculations, and consider using a math library like MathPHP for more complex operations.

// Example: Using built-in math functions to optimize mathematical tasks in PHP

// Calculate the square root of a number using built-in function
$number = 25;
$squareRoot = sqrt($number);

echo "Square root of $number is: $squareRoot";
