Are there any specific PHP functions or libraries that are recommended for implementing a timer in this scenario?

To implement a timer in PHP, you can use the `time()` function to get the current timestamp before starting the task and then calculate the elapsed time after the task is completed. You can also use the `microtime()` function for more precise timing if needed. Another option is to use the `Timer` class from the `symfony/stopwatch` library for more advanced timing functionalities. 

// Using time() function
$start_time = time();
// Perform the task here
$end_time = time();
$elapsed_time = $end_time - $start_time;
echo "Elapsed time: " . $elapsed_time . " seconds";

// Using microtime() function
$start_time = microtime(true);
// Perform the task here
$end_time = microtime(true);
$elapsed_time = $end_time - $start_time;
echo "Elapsed time: " . $elapsed_time . " seconds";

// Using symfony/stopwatch library
use Symfony\Component\Stopwatch\Stopwatch;

$stopwatch = new Stopwatch();
$stopwatch->start('task_timer');
// Perform the task here
$event = $stopwatch->stop('task_timer');
echo "Elapsed time: " . $event->getDuration() / 1000 . " seconds";
