注: mode was added in PHP 4.0.5.
ob_gzhandler() is intended to be
used as a callback function for
ob_start() to help facilitate sending gz-encoded data
to web browsers that support compressed web pages. Before ob_gzhandler() actually sends compressed
data, it determines what type of content encoding the browser
will accept ("gzip", "deflate" or none at all) and will
return it's output accordingly. All browsers are supported
since it's up to the browser to send the correct header
saying that it accepts compressed web pages.
注: You cannot use both ob_gzhandler() and ini.zlib.output_compression. Also note that using ini.zlib.output_compression is preferred over ob_gzhandler().
See also ob_start() and
ob_end_flush().
