What is the recommended method to measure the time taken for a PC to transfer data to a web server using PHP?

To measure the time taken for a PC to transfer data to a web server using PHP, you can use the microtime() function to capture the current time before and after the data transfer process, and then calculate the difference to determine the elapsed time.

$start_time = microtime(true);

// Perform data transfer process here

$end_time = microtime(true);
$elapsed_time = $end_time - $start_time;

echo "Time taken for data transfer: " . $elapsed_time . " seconds";
