网页开启gzip压缩以后,其体积可以减小20%~90%,可以节省下大量的带宽,从而减少页面响应时间,提高用户体验。

php配置改法:

复制代码 代码如下:

zlib.output_compression = On
;开启gzip功能

zlib.output_compression_level = 4
;gzip压缩级别,1~9,建议3~5

;zlib.output_handler =
;gzip压缩方式,建议注释

php文件改法:

建议在页面开头写上,可以写到头部公共文件

复制代码 代码如下:

if( !headers_sent() && // 如果页面头部信息还没有输出
extension_loaded("zlib") && // 而且php已经加载了zlib扩展
strstr($_SERVER["HTTP_ACCEPT_ENCODING"],"gzip")) //而且浏览器接受GZIP
{
  ini_set('zlib.output_compression', 'On');
  ini_set('zlib.output_compression_level', '4');
}
