I finished implementing chunked output buffering, and made ob_gzhandler() compatible with it - so now chunked output compression is possible with PHP. In my testing, supplying a 4KB buffer appears to be almost as efficient (compression-ratio wise) as compressing the entire buffer in one go. Obviously, it's much more efficient memory-wise. For instance, a phpinfo() script:

no compression                          40KB
ob_start("ob_gzhandler")                        5KB
ob_start("ob_gzhandler", 4096)          5.5KB
ob_start("ob_gzhandler", 64)            10KB

Read: You can now efficiently have your outgoing PHP/HTTP traffic compressed with good compression ratios without sacrificing memory. Comments extremely welcome - and if people can also test it and let me know whether it works for them, it'd be great.
