PHP includes its own output compression handler, which is not only faster but also maintained by PHP team and (!!!) supports "deflate" compression in addition to "gzip". We can only benefit from using this handler.

There might be a problem: the callback handler may return FALSE in case
it doesn't want to change the content. I think this might happen, when
ob_gzhandler detects that the client cannot handle transfer compression.

PS: Since you created a special handler to correct the content-lenght
header I wonder why you didn't use the PHP class as a fallback if the
PHP extension isn't available.
