How can PHP scripts be designed to handle user aborts, such as closing the browser, without causing data integrity issues in the database or on the server?

When a user aborts a PHP script, such as by closing the browser, it can lead to data integrity issues if the script was in the middle of processing database transactions or other critical operations. To handle this, you can use connection handling functions in PHP to detect when a user aborts and gracefully handle the situation by rolling back any incomplete transactions or releasing any resources being used. 

// Register a shutdown function to handle user aborts
register_shutdown_function(function() {
    if (connection_aborted()) {
        // Handle user abort here, such as rolling back transactions or releasing resources
        // Example: $db->rollback();
    }
});

// Your PHP script code here
// Example: $db->beginTransaction();
