ThinkPHP中PATHINFO模式优化,thinkphppathinfo

ThinkPHP 3.1.2官方手册 第16.2章节 《隐藏index.php》中提到在Ngnix中隐藏index.<span>php实现SEO友好的方法,其中使用了如下的代码

location </span>/<span> {
   </span><span>if</span> (!-e <span>$request_filename</span><span>) {
      rewrite  </span>^(.*)$  /index.php?s=$1<span>  last;
      </span><span>break</span><span>;
    }
}
这种方法性能非常差,因为会对图片文件也进行文件存在判断,增加了磁盘IO开销 ,在《Nginx HTTP Server》一书中提到了种优化方法, 也就是修改为下面的那段代码。

location </span>/<span> {
   </span><span>if</span> (<span>$request_filename</span> ~* "\.(gif|jpg|jpeg|png|swf|js|css)"<span>) {
      </span><span>break</span>;    <span>//</span><span> 图片文件不再进行重写,也不再进行文件存在判断,能够避免Nginx进行无用检查,降低磁盘IO开销</span>
<span>   }

   </span><span>if</span> (!-e <span>$request_filename</span><span>) {               
      rewrite </span>^(.*)$ /index.php?s=$1<span> last;
      </span><span>break</span><span>;
   }
}

</span><span>#</span><span> 简单到没有技术含量,但是效果好~</span>

thinkPHP中的pathinfo模式是怎实现的?

PATH_INFO 是一个 CGI 1.1 环境变量
pathinfo模式就是将路径中的每一节对应于预先设定的变量
即以位置来决定含义,有如下标数组
$_SERVER['PATH_INFO']这个是原型

然后是正则表达式或者字符串函数获取 参数
 

thinkphp URL常用模式

这个用哪种了,主要看运营那边的seo需求了和你当前服务器的支持了,说白了thinkphp URL请求模式就是针对seo优化这块的,tp默认的是pathinfo 模式,用什么自己选择了
