Why Does My PHP Query Method Throw a 'Call to fetch_assoc() on Non-Object' Fatal Error?

Fatal Error in Query Method: Call to fetch_assoc() on Non-Object

In a PHP application, a fatal error in a query method is often caused by a non-object error. This error can occur when attempting to access a member function of a non-existent object, such as $result->fetch_assoc().

To resolve this issue, consider the following steps:

• Check Query Execution: Ensure that the database query is executed successfully. The query result should be validated, and any errors should be handled by throwing an exception or logging the error message.
• **Examine $result:** Verify that $result is actually a mysqli result set object. If it is not, it may indicate a problem with the query execution or connection.
• Handle Errors Gracefully: Implement error handling to capture potential errors during query execution. If an error occurs, an exception or error message can be thrown to provide more context to the developer.
• Review Database Connection: Confirm that the application is successfully establishing and maintaining a connection to the database. Any connection issues can prevent query execution and lead to non-object errors.

By following these steps, you can troubleshoot and resolve the fatal error related to calling a member function on a non-object in PHP, ensuring that your database queries are executed correctly and errors are handled appropriately.
