How can PHP be utilized to improve accuracy in timing calculations for scripts?

When executing scripts in PHP, timing calculations can sometimes be inaccurate due to varying server loads and execution times. To improve accuracy in timing calculations, we can utilize the `microtime()` function in PHP to measure the exact time taken for script execution. 

$start_time = microtime(true);

// Your script logic here

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

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