ob_gzhandler
ob_start callback function to gzip output buffer
(PHP 4 >= 4.0.4, PHP 5)
string ob_gzhandler ( string buffer, int mode )
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 its 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. If a browser
doesn't support compressed pages this function returns FALSE.
Examples
Example 1689. ob_gzhandler() example
<?php
ob_start("ob_gzhandler");
?>
<html>
<body>
<p>This should be a compressed page.</p>
</html>
<body>
Notes
ob_gzhandler() requires the zlib extension.
You cannot use both ob_gzhandler() and zlib.output_compression. Also note that using zlib.output_compression is preferred over ob_gzhandler().
