I have been creating a site and checking it's speed through gtmetrix.com. I used the following .htaccessfile to compress the .js, .cssand many more files.
我一直在创建一个站点并通过gtmetrix.com检查它的速度。我使用以下.htaccess文件来压缩.js, .css和更多文件。
<ifModule mod_gzip.c>
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*

But when I run the page test it shows the following -----
但是当我运行页面测试时，它显示以下内容 -----
Compressing the following resources with gzip could reduce their transfer size by 882B (48% reduction).
Compressing http://wooflux.co.cc/ could save 645B (48% reduction).
Compressing http://wooflux.co.cc/style.css could save 237B (51% reduction).
But I have done gzipcompression on my .htaccessfile. I don't what is getting wrong here, and by the way I'm very new to this coding style. So please let me know if I'm doing any error or not.
但是我已经gzip对我的.htaccess文件进行了压缩。我不知道这里出了什么问题，顺便说一下，我对这种编码风格很陌生。所以请让我知道我是否在做任何错误。

I have not used mod_gzip but here is my .htaccess I use to gzip .js, .css and other files via mod_deflate:
我没有使用过 mod_gzip，但这是我用来通过 mod_deflate gzip .js、.css 和其他文件的 .htaccess：
#Gzip
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x- javascript application/javascript
</ifmodule>
#End Gzip
In case you are not already aware of it, Firebugis very useful for checking if downloaded content is gzipped. Click on the "Net" tab in Firebug and then do shift-f5 to get Firefox to reload all the .js and .css files so they show in the Net panel. Click the "+" next to the .js or .css file and click the "Headers" tab. If the response is gzipped you will see "Content-Encoding gzip" in the Response Headers section. I image the IE, Safari, and Chrome equivalents offer the same ability.
如果您还没有意识到，Firebug对于检查下载的内容是否被 gzip 非常有用。单击 Firebug 中的“Net”选项卡，然后执行 shift-f5 以让 Firefox 重新加载所有 .js 和 .css 文件，以便它们显示在 Net 面板中。单击 .js 或 .css 文件旁边的“+”，然后单击“标题”选项卡。如果响应是 gzip 压缩的，您将在响应标头部分看到“Content-Encoding gzip”。我想象 IE、Safari 和 Chrome 等价物提供相同的功能。
There is one gotcha regarding gzipping .js and .css files on IE6to watch out for. I think it is only applicable to IE6 SP1 users.
关于在 IE6 上压缩 .js 和 .css 文件有一个问题需要注意。我认为它只适用于 IE6 SP1 用户。

Here is a syntax to use with file extensions.
这是用于文件扩展名的语法。
<IFModule mod_deflate.c>
<filesmatch "\.(js|css|html|jpg|png|php)$">
SetOutputFilter DEFLATE
</filesmatch>
</IFModule>

In my case, mod_gzip or mod_deflate was not working even after making it enabled and writing it in the htaccess file.
就我而言，即使启用 mod_gzip 或 mod_deflate 并将其写入 htaccess 文件后，它也无法正常工作。
Then, I was end up using 'ob_gzhandler' in my php file, which helped me to compress my php and html files. This is not as good as mod_gzip or mod_deflate, but serve you temporarily in case if you can't get a luck on other.
然后，我最终在我的 php 文件中使用了 'ob_gzhandler'，它帮助我压缩了我的 php 和 html 文件。这不如 mod_gzip 或 mod_deflate，但可以暂时为您服务，以防万一您在其他方面运气不佳。
The code which I used on my index.php file at top, before loading anything is,
在加载任何内容之前，我在顶部的 index.php 文件中使用的代码是，
<? ob_start("ob_gzhandler"); ?>
