How do I see my code that has PHP (collecting data) as a user ?

Question

Example: If I made a survey.
All the PHP and everything Is set up to collect data about the Survey.
If I wanted to see my code (like I'm the user), how would I do that?

Maybe If I was editing the code online, Preview the code, then copy the Link maybe?
