Let's talk about the solution to the problem that PHP database hobby cannot be displayed.

In a PHP project, if you encounter the problem that the database hobby cannot be displayed, this may be due to a variety of reasons. Although this error can be quite annoying, fortunately, there are some simple steps we can take to resolve it.

The following are some reasons that may cause the database hobby to not be displayed, and how to solve these problems:

1. Database connection error

First, you need to check whether your database connection is configured correctly. You should confirm that you are using the correct hostname, database name, username, and password to connect to the MySQL database. If these are correct, then you should take a look at whether the PHP code is establishing the database connection correctly. This could be a simple error, like wrong characters in the connection string, which could prevent your program from connecting to the database hobby.

2. The database table does not exist

If you have confirmed that your database connection is correct, the next step is to confirm whether there is a hobby table in the database. Even if you create the table through code, it may not exist. You can enter show tables at the MySQL command prompt to see if a table named hobby exists in the current database. If the table does not exist, then you need to create the table in the command prompt or create the table in your PHP code.

3. The database connection character set setting is incorrect

If the connection has been established and the hobby table also exists, then the inconsistency with the connection character set setting may affect to your database. This can cause special characters to appear garbled in queries. If you encounter this situation, you should set the correct character set for the database connection. You can try to modify your pdo_mysql.default_charset configuration item to ensure that the character set used is set correctly.

4. The database server port setting is incorrect

If your MySQL server port is not configured correctly, you will not be able to establish a connection and will not be able to display hobby database. Make sure you specify the port correctly in the connection string.

5. Database access restrictions

If you apply for a database hosting service, you may not be able to access the database hobby. In some cases it is recommended to contact your hosting provider to resolve the issue.

In short, the above are some reasons that may cause your PHP code to fail to display the database hobby. These errors often cause the code to not run properly, but if you follow the above steps to check the possibilities one by one and add the necessary fixes to the code, you can solve the problem quickly.

Hope the above solutions can help you and solve your problem.
