How do you handle errors when creating a MySQL database using PHP?

When creating a MySQL database using PHP, you can handle errors by checking the return value of the mysqli_query() function. If the mysqli_query() function returns false, it indicates an error occurred during the query execution. You can then use error handling techniques such as mysqli_error() or mysqli_errno() to get detailed error information. Additionally, you can set up a custom error handling function using mysqli_set_error_handler() to define how errors should be handled. Another approach is to use the try-catch block with exception handling to catch and handle any exceptions that may occur during the database creation process. Proper error handling helps in diagnosing and resolving issues during database operations.
