Has there been a change to the way output buffering works?
The manual states for ob_get_contents()
This will return the contents of the output buffer or FALSE, if output
buffering isn't active.
But the following works in php4.4.4 and php5.2.6 whether output buffering is
on or not

Right!
With zlib compression ob_start() or similar seems to get called before the

I see three options here:
#1 Call ob_start/ob_get_contents/ob_flush and repeat that a *LOT* within
your script, so that you are buffering only a few lines of text at any

Hi,
When using ob_start(), the output is buffered and not sent till
ob_end_flush() is called or got to end of the script. Also before flushing
you can get the buffer contents by ob_get_contents().
