为什么php gzip输出不适合我？ [英] Why is php gzip output not working for me?
问题描述
我有此代码：
<?php
// Include this function on your pages
function print_gzipped_page() {
global $HTTP_ACCEPT_ENCODING;
if( headers_sent() ){
$encoding = false;
}elseif( strpos($HTTP_ACCEPT_ENCODING, 'x-gzip') !== false ){
$encoding = 'x-gzip';
}elseif( strpos($HTTP_ACCEPT_ENCODING,'gzip') !== false ){
$encoding = 'gzip';
}else{
$encoding = false;
}
if( $encoding ){
$contents = ob_get_contents();
ob_end_clean();
header('Content-Encoding: '.$encoding);
print("\x1f\x8b\x08\x00\x00\x00\x00\x00");
$size = strlen($contents);
$contents = gzcompress($contents, 9);
$contents = substr($contents, 0, $size);
print($contents);
exit();
}else{
ob_end_flush();
exit();
}
}
// At the beginning of each page call these two functions
ob_start();
ob_implicit_flush(0);
// Then do everything you want to do on the page
?>
<html>
<body>
<p>This should be a compressed page.</p>
</html>
<body>
<?
// Call this function to output everything as gzipped content.
print_gzipped_page();
?>
但是当我查看页面源代码时，我看不到压缩代码。
But when i view the page source, I'm not seeing compressed code. WHat's wrong?
推荐答案
错误？
WHat's wrong?
可能没什么。 GZIP压缩是服务器和浏览器之间完全透明的过程。服务器将压缩，浏览器将自动解压缩数据。
probably nothing. GZIP compression is a completely transparent process between the server and the browser. The server will compress, and the browser will automatically uncompress the data. In the end result (= the HTML page's source code), nothing will change.
使用Firebug或Chrome开发者工具等工具来查看响应是否真的被压缩。
Use tools like Firebug or Chrome's developer tools to see whether the response was actually compressed.
在Chrome的开发人员工具的网络标签中，压缩响应将如下所示：
In Chrome's Developer tools' "Network" tab, a compressed response will look something like this:
