How can monitoring and logging the execution time of PHP scripts help identify performance bottlenecks related to session handling?

Monitoring and logging the execution time of PHP scripts can help identify performance bottlenecks related to session handling by tracking how long it takes for the script to execute when interacting with session data. This can reveal if the session handling process is causing delays or inefficiencies in the script execution, allowing developers to optimize the session handling code or consider alternative approaches to improve performance. 

// Start measuring script execution time
$start_time = microtime(true);

// Session handling code here

// End measuring script execution time
$end_time = microtime(true);
$execution_time = $end_time - $start_time;

// Log the execution time
error_log("Script execution time: " . $execution_time . " seconds");
