What are the best practices for naming database fields to avoid conflicts or confusion in PHP applications?

When naming database fields in PHP applications, it is important to follow best practices to avoid conflicts or confusion. One common approach is to use descriptive and unique names that clearly indicate the purpose of the field. Additionally, it is recommended to avoid using reserved words or special characters in field names to prevent potential issues with queries or data manipulation.
