PHP programmer’s pervasive problem, Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at
If you are a php programmer, some times, you’ll face this problem. You’ll see this on your web page:
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at …bla..bla..bla..
After trying some methods, i finally know that this caused by an error in code writing. It’s about whitespaces. Try this solutions, although i cannot guarantee that it will succeed for you, but i have tried it and it’s okay. Here’s the solution:
- Dont’t let a whitespace exist before the <?php that precede the session_start().
- Save the php file as ANSI. If you use Notepad++, you could click Format > ANSI.
- Some people suggest UTF-8 without BOM, but i manage to fix everything without applying this.
If you have more solutions, just add it on the comment form.
