How can PHP be used to handle situations where a time period has passed but is still being recognized as current?

When handling situations where a time period has passed but is still being recognized as current, you can use PHP to compare the current time with the target time and adjust accordingly. One way to do this is by using the `strtotime` function to convert the target time into a Unix timestamp and then comparing it with the current Unix timestamp obtained using `time()` function. 

$target_time = strtotime('2022-01-01 00:00:00');
$current_time = time();

if ($current_time > $target_time) {
    // Time period has passed
    echo "Time period has passed.";
} else {
    // Time period is still current
    echo "Time period is still current.";
}
