output buffering

I've just committed the use of output buffering in CVS.  This is 
actually fairly neat.

On Mandrake Linux 9.2, using PHP 4.3.3, I tested index.php and 
enterbug.php (the "how do i report a bug" thing) encoded and not and 
the results are:

index.php: 5277 bytes and 1938 bytes compressed
enterbug.php: 7572 bytes and 303 bytes compressed

On OS X 10.3 using PHP 4.3.2, I tested the same two files with these 
results:

index.php: 5431 bytes and 2019 bytes compressed
enterbug.php: 8367 bytes and 3555 bytes compressed

The slight difference in the un-encoded size for enterbug.php is that 
the Linux one is using the default theme and the OS X one is using the 
"blue" theme.

I couldn't explain why it got compressed so highly on the Linux machine 
for enterbug.php.. I did it twice just to make sure.  Could be 
different versions of gzip (both are the same version of apache).

Regardless, I think this is pretty cool.  =)  Just had to share that.

Oh, and it's configurable so if your server (ie. IIS maybe?) doesn't 
support compression and output buffering doesn't work well in PHP, it 
can be turned off.
