OB_GZHANDLER(3) 1 OB_GZHANDLER(3)ob_gzhandler - ob_start callback function to gzip output bufferSYNOPSIS
string ob_gzhandler (string $buffer, int $mode)
DESCRIPTION ob_gzhandler(3) is intended to be used as a callback function for ob_start(3) to help facilitate sending gz-encoded data to web browsers
that support compressed web pages. Before ob_gzhandler(3) 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.
PARAMETERS
o $buffer
-
o $mode
-
RETURN VALUES EXAMPLES
Example #1
ob_gzhandler(3) example
<?php
ob_start("ob_gzhandler");
?>
<html>
<body>
<p>This should be a compressed page.</p>
</body>
</html>
NOTES
Note
ob_gzhandler(3) requires the zlib extension.
Note
You cannot use both ob_gzhandler(3) and zlib.output_compression. Also note that using zlib.output_compression is preferred over
ob_gzhandler(3).

NOTES
Note
If you want to output binary data, such as an image, using PHP 4.3.0 or later, a Content-Type: header must be set using header(3)
before any binary data is sent to the client (e.g. header("Content-Type: image/png")). If Content-Type: header is sent, output char-
acter encoding conversion will not be performed.
Note that if 'Content-Type: text/*' is sent, the content body is regarded as text; conversion will take place.
If you want to output binary data, such as an image, using PHP 4.2.x or earlier, you must set output encoding to "pass" using
mb_http_output(3).
