Use
echo ob_get_level() . "<br/>";
to find out how many levels of output buffering you are wrapped in.
Whether output buffering is set to start automatically, and whether output
buffering is on right now are two different things:
ob_end_clean();
echo ob_get_level() . "<br/>";
echo ini_get('output_buffering') . "<br/>";

Thanks David. After taking another look at the description for ob_start() I
began to suspect there was a difference, but the manual doesn't mention
anything about it. And the fact they use the same terminolgy for both the
settings and the functions is confusing. I can see from tests that the
htaccess/ini settings have no obvious effect on the ob functions (maybe
buffer size?).
Cheers
Arno
