What is the difference between using mktime() and time() to get the current timestamp in PHP?

The main difference between using mktime() and time() to get the current timestamp in PHP is that mktime() allows you to specify a custom timestamp based on the parameters you pass to it, while time() simply returns the current timestamp. If you need to get the current timestamp, it is more straightforward to use time().

// Using time() to get the current timestamp
$current_timestamp = time();
echo $current_timestamp;
