How can PHP functions be optimized to handle time calculations more efficiently?

One way to optimize PHP functions for time calculations is to avoid unnecessary function calls and loops. Instead of repeatedly calling functions like date() or strtotime(), store the result in a variable and reuse it when needed. Additionally, consider using built-in PHP functions like DateTime for more complex time calculations as they are optimized for performance. 

// Example of optimizing time calculations using DateTime

$currentTime = new DateTime();
$futureTime = clone $currentTime;
$futureTime->modify('+1 hour');

// Now you can use $currentTime and $futureTime for further calculations
