Are there any best practices for handling microtime functions in PHP?

When working with microtime functions in PHP, it is important to handle them carefully to ensure accurate timing measurements. One best practice is to use microtime(true) to get the current Unix timestamp with microseconds included. This ensures precision in timing calculations. Additionally, it is recommended to store the start time in a variable before performing any operations to avoid discrepancies due to the time passing during execution. 

// Get the start time
$start_time = microtime(true);

// Perform some operations

// Get the end time
$end_time = microtime(true);

// Calculate the elapsed time
$elapsed_time = $end_time - $start_time;

echo "Elapsed time: " . $elapsed_time . " seconds";
