What are some strategies for troubleshooting PHP navigation issues within a website?

Issue: One common navigation issue in PHP websites is when the navigation links are not directing to the correct pages or are not displaying properly. This can be caused by incorrect file paths or syntax errors in the navigation code. Fix: To troubleshoot this issue, ensure that the file paths in the navigation links are correct and that the syntax of the PHP code generating the navigation is error-free. Additionally, check for any typos or missing quotation marks in the code.
