Why Aren't My MySQLi Queries Throwing Exceptions, and How Can I Fix It?

Enhancing Error Handling with MySQLi Exceptions

In an attempt to simplify error handling, you're encountering difficulties in converting MySQLi query errors into exceptions.

Problem Description:

Despite employing mysqli_report(MYSQLI_REPORT_STRICT) in conjunction with procedural MySQLi functions within a custom wrapper class, query failures still result in neither warnings nor exceptions being raised, necessitating manual return value checks for mysqli_query().

Answer:

To resolve this issue and force MySQLi to throw exceptions, use the following line:

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

Explanation:

mysqli_report()'s default behavior is to report both warnings and errors. However, by setting the MYSQLI_REPORT_ERROR flag, MySQLi is instructed to only report errors, which aligns with the desired behavior of throwing exceptions.

Important Note:

Avoid wrapping every query in a try-catch block, as it's considered best practice to utilize a site-wide error handler to manage the majority of errors rather than handling them in specific locations.
