PHP+.htaccess实现全站静态HTML文件GZIP压缩传输(一)
apache的强大终于超出了我的想象,仅仅蜻蜓点水般触及了一点php皮毛,这点皮毛就在我原有的知识库基础上爆炸开来,好像PN结的“雪崩击穿”一样,让我想到了多种技术结合无限的应用前景。
由于九州未来的服务器限制流量,那么减少流量负载也就能减少金钱支出。
如何减少流量,最方便的办法就是用Gzip压缩,这个apache的gzip压缩是靠一个叫做zlib的类库和gzip的模块(mod_gzip.c)完成的,这玩意专门有一帮牛人研究,因为gzip本身就大名鼎鼎的,并且具有高压缩率开源的压缩原理,所以我们的开源apache才会采用这种开源的压缩技术。
恩,这个.htaccess也是apache的一个牛比东西,太强大了,也是根据你的apache安装了什么模块而决定你这个文件里面可以写什么东西,比如你安装了URL重写模块(Module mod_rewrite.c)的话你就可以写一些URL重写代码来实现你的文件重写。
知识普及完毕。。。。
进入正题。
如何让自己的全站的真实的静态的html文件,变成gzip传输的呢?
为了理解方便,我给大家写了一个简单的php程序。
首先我们建立一个采用gzip压缩算法的l.php,在该文件中读入xxx.html并显示出来,然后再在.htaccess里面重写xxx.html到1.php就可以了。简单吧。由于我们的服务器认为.htaccess的优先级最高,所以访问xxx.html的时候没有访问到这个静态文件,反而访问到了1.php.
下面是我的代码:(读入index2.html,然后重写之)
.htaccess:
复制代码 代码如下:
# 将 RewriteEngine 模式打开
RewriteEngine On
RewriteBase /
RewriteRule index2\.html l.php?fn=index2.html
1.php
复制代码 代码如下:
$phpver = phpversion();
$useragent = (isset($_SERVER["HTTP_USER_AGENT"]) ) ? $_SERVER["HTTP_USER_AGENT"] : $HTTP_USER_AGENT;
if ( $phpver >= '4.0.4pl1' && ( strstr($useragent,'compatible') || strstr($useragent,'Gecko') ) )
{
if ( extension_loaded('zlib') )
{
ob_start('ob_gzhandler');
}
}
else if ( $phpver > '4.0' )
{
if ( strstr($HTTP_SERVER_VARS['HTTP_ACCEPT_ENCODING'], 'gzip') )
{
if ( extension_loaded('zlib') )
{
$do_gzip_compress = TRUE;
ob_start();
ob_implicit_flush(0);
header('Content-Encoding: gzip');
}
}
}
?>
$rfile = addslashes(dirname(dirname(__FILE__))).'/'.'./httpdocs/'.$_REQUEST['fn'];
echo READ_FILE_CONTENTS($rfile);
function READ_FILE_CONTENTS($file)
{
if(!function_exists("file_get_contents"))return file_get_contents($file);
$ifile = fopen($file,"r");
$contents = false;
if($ifile) while (!feof($ifile)) $contents .= fgets($ifile);
fclose($ifile);
return $contents;
}
?>
// Compress buffered output if required and send to browser
if ( $do_gzip_compress )
{
//
// Borrowed from php.net!
//
$gzip_contents = ob_get_contents();
ob_end_clean();
$gzip_size = strlen($gzip_contents);
$gzip_crc = crc32($gzip_contents);
$gzip_contents = gzcompress($gzip_contents, 9);
$gzip_contents = substr($gzip_contents, 0, strlen($gzip_contents) - 4);
echo "\x1f\x8b\x08\x00\x00\x00\x00\x00";
echo $gzip_contents;
echo pack('V', $gzip_crc);
echo pack('V', $gzip_size);
}
exit;
?>
实际上这个东西能用更好的方法解决,就是用这个
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /xxx/xxx.php [L]
但是我还没研究出来怎么处理这个%{REQUEST_FILENAME},还望高手赐教。
