What role does understanding file paths and form actions play in PHP development to avoid getting stuck on a blank page?

Understanding file paths and form actions in PHP development is crucial to avoid getting stuck on a blank page. Incorrect file paths can lead to errors in including files or accessing resources. Similarly, incorrect form actions can result in the form data not being processed correctly. By ensuring that file paths are correct and form actions point to the appropriate PHP scripts, developers can prevent encountering blank pages and ensure the proper functioning of their PHP applications.
