What are the best practices for naming database fields in PHP to avoid errors?

When naming database fields in PHP, it is important to follow best practices to avoid errors. One common practice is to use lowercase letters and underscores to separate words in field names. Additionally, it is recommended to use descriptive and meaningful names that accurately represent the data being stored in the field. By following these best practices, you can create more readable and maintainable database structures in your PHP applications.
