What are the best practices for naming PHP classes and files to avoid confusion and errors?

To avoid confusion and errors when naming PHP classes and files, it is important to follow naming conventions and best practices. Use descriptive and meaningful names that accurately reflect the purpose of the class or file. Avoid using special characters, spaces, or reserved keywords in the names. Additionally, adhere to the PSR-4 autoloading standard for class naming and file organization.
