MySQLi or Die: Is Script Termination Always Necessary?

Mysqli or Die: Must It Always Lead to Termination?

In MySQLi, the mysqli_query() function is often accompanied by the or die() statement to handle errors. However, this approach raises the question: Is it mandatory to kill the script in case of an error?

Alternatives to or die()

PHP offers several alternatives to the abrupt termination caused by or die(). One option is to configure mysqli to throw exceptions on errors. By using the mysqli_report function and setting the flag to MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT, any MySQLi error will trigger an exception.

This approach allows for more graceful error handling, such as logging the error to a specific table. The following code demonstrates how to log errors using a custom function:

function log_mysqli_error($query, $error) {
    // Write the error to a log file or table
}

try {
    $update_result = mysqli_query($link, $sql_update_login);
} catch (mysqli_sql_exception $e) {
    log_mysqli_error($e->getQuery(), $e->getMessage());
}

Advantages of Exception Handling

Using exceptions offers several benefits:

• Improved Error Reporting: Exceptions provide detailed information about the error, including its source and line number.
• Graceful Error Handling: Errors can be caught and handled appropriately, allowing the script to continue execution where possible.
• Reduced Code Complexity: Exception handling simplifies code by eliminating the need for extensive or die() statements.

Conclusion

While mysqli or die was once a common practice, it has become outdated due to its limitations and negative consequences. By leveraging exception handling and custom error logging, developers can manage MySQLi errors more effectively, ensuring the stability and reliability of their applications.
