How can timestamping and sleep functions be used in PHP scripts to analyze and troubleshoot potential concurrency issues in database operations?

Concurrency issues in database operations can be analyzed and troubleshooted by using timestamping and sleep functions in PHP scripts. By timestamping the start and end of database operations, developers can track the order of execution and identify any potential race conditions. Additionally, introducing sleep functions between database operations can help simulate concurrent access and reveal any issues with data consistency or locking. 

// Timestamp the start of the database operation
$start_time = microtime(true);

// Perform database operation
// Example: INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2');

// Timestamp the end of the database operation
$end_time = microtime(true);

// Calculate the duration of the database operation
$duration = $end_time - $start_time;

// Introduce a sleep function to simulate concurrent access
sleep(1); // Sleep for 1 second before proceeding to the next database operation
