ob_gzhandler

(PHP 4 >= 4.0.4, PHP 5)

ob_gzhandlerob_start callback function to gzip output buffer

说明

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.

参数

buffer

mode

返回值

更新日志

版本 说明
4.0.5 The mode parameter was added.

范例

Example #1 ob_gzhandler() example

<?php

ob_start
("ob_gzhandler");

?>
<html>
<body>
<p>This should be a compressed page.</p>
</html>
<body>

注释

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().
