To troubleshoot PHP code that results in a blank webpage, checking the browser source code can help identify any syntax errors or issues with the PHP code that may be causing the problem. By inspecting the source code in the browser, you can see if the PHP code is generating any errors or if the output is not being displayed correctly. This can help pinpoint the issue and guide you in fixing the problem.
