PHP's ob_flush() causing error

When I call PHP's ob_flush() function on my localhost (via MAMP) I get the following error:

Notice: ob_flush() [ref.outcontrol]: failed to flush buffer. No buffer to flush.

The only solution I can find is to prefix it with @, but this doesn't seem like a real solution to me. What's causing the problem?

If you want to use ob_flush you must first call ob_start() - desirably at the top of your page.

Not sure if it fits your needs but you might want to also try the plain old flush(), just guessing.

The error message would seem to imply that you're not actually using output buffering when you call ob_flush(). Have you called ob_start() previous to invoking ob_flush()?
