I am using xampp 1.6.3 and notepad++ 4.7.2 and later 5.9.8.

In a page that we redirect to this page using header("Location:page.php"), the IDE or something else put a \n or RETURN or when it turn to html <br>. I mean before session_start() there is an unwanted html character which cause session not working. I found out this when I saw html source, not in the IDE)

What do I have to do right now?

  • If said "IDE" doesn't have a setting for those automatic additions, then there's no way to "prevent" it. At least not the injected `
    ` tags. For whitespace issues (in 2012!) there are automated [tools for post-processing](http://stackoverflow.com/a/8584233/345031).     – mario Mar 08 '12 at 21:34

I believe you have some includes and one of the included files have some extra characters at the end. Please trim the files off any extra whitespace. Also it is a good practice to omit the ending php tag to avoid such scenarios.

If you're unable to find the offending output, you could try to work with output buffering as a workaround.
