I have a production website for which I do not have access to the full file system; specifically, I can't view the error log. The site is running under IIS. However, I can edit the php ini. There is a page that is not loading. I do not want to enable errors across the entire site, as I don't want to risk any sensitive information being revealed.
Is there a way to make PHP output all errors wrapped in a <!-- --> (a comment) and not make it visible to most users unless they check the source?

Yes there is a built-in function. What you are looking for is set_error_handler. Juste copy/paste Example #1 from PHP doc and replace markup by your HTML comment markup.
