ob_gzhandler
(PHP 4 >= 4.0.4, PHP 5, PHP 7)
ob_gzhandler — ob_start callback function to gzip output buffer
Description
$buffer
, int $mode
) : string
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 #1 ob_gzhandler() example
<?php
ob_start("ob_gzhandler");
?>
<html>
<body>
<p>This should be a compressed page.</p>
</body>
</html>
Notes
Note:
ob_gzhandler() requires the zlib extension.
Note:
You cannot use both ob_gzhandler() and zlib.output_compression. Also note that using zlib.output_compression is preferred over ob_gzhandler().
See Also
- ob_start() - Turn on output buffering
- ob_end_flush() - Flush (send) the output buffer and turn off output buffering
