How can tools like Fiddler be used to troubleshoot issues with data retrieval in PHP scripts?

When troubleshooting issues with data retrieval in PHP scripts, tools like Fiddler can be used to inspect the HTTP requests and responses between the client and server. By analyzing the headers, cookies, and content of the requests, developers can identify any errors or inconsistencies that may be causing the data retrieval issues. Additionally, Fiddler can help pinpoint performance bottlenecks and optimize the data retrieval process for improved efficiency.
