How can the impact of server processing time on script execution time be accounted for when using microtime() in PHP?

The impact of server processing time on script execution time can be accounted for by calculating the difference between the current time and the start time of the script using PHP's microtime() function. This allows you to accurately measure the actual time taken for the script to execute, regardless of server processing delays.

// Start time of the script
$start_time = microtime(true);

// Your script code goes here

// End time of the script
$end_time = microtime(true);

// Calculate the total execution time
$execution_time = $end_time - $start_time;

echo "Script execution time: " . $execution_time . " seconds";
