What are some best practices for handling timing calculations in PHP scripts that involve database interactions?

When handling timing calculations in PHP scripts that involve database interactions, it is important to consider the time taken by database queries and processing. One best practice is to measure the time before and after the database interaction to accurately calculate the execution time. This can help in optimizing the script and identifying any performance bottlenecks. 

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

// Perform database interaction
// Example: fetching data from a database
$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

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

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

// Output the execution time
echo "Execution time: " . $execution_time . " seconds";
