How can PHP developers ensure that their scripts accurately capture the start and end times of FTP uploads?

To accurately capture the start and end times of FTP uploads in PHP, developers can use the `microtime()` function to get the current timestamp with microseconds precision before and after the FTP upload process. By calculating the difference between these two timestamps, developers can accurately measure the duration of the upload process.

// Start time
$start_time = microtime(true);

// FTP upload process
// Your FTP upload code here

// End time
$end_time = microtime(true);

// Calculate duration
$duration = $end_time - $start_time;
echo "FTP upload took " . $duration . " seconds.";
