linux下php安装pathinfo

在Nginx.conf配置中,添加
location ~ [^/]\.php(/|$){
    fastcgi_pass  unix:/tmp/php-cgi.sock;
    fastcgi_index index.php;
    fastcgi_split_path_info ^(.+\.php)(.*)$;
    fastcgi_param PATH_INFO $fastcgi_path_info;
    include fastcgi.conf;
    include pathinfo.conf;
}

在Nginx低版本中,是不支持PATHINFO的,但是可以通过在Nginx.conf中配置转发规则实现。
location / {    if (!-e $request_filename) {
        rewrite  ^(.*)$  /index.php?s=/$1  last;
        break;
    }
}

一个完整示例,请根据自己服务器加以修改
server {
        listen       80;
        server_name  www.dolphinphp.com *.dolphinphp.com;
        root   "/home/www/wwwroot/dolphinphp";
        location / {            index  index.html index.htm index.php;                #主要是这一段一定要确保存在
                if (!-e $request_filename) {
                    rewrite  ^(.*)$  /index.php?s=$1  last;                    break;
                }                #结束
            #autoindex  on;
        }
        location ~ \.php(.*)$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info  ^(.+\.php)(.*)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO  $fastcgi_path_info;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}


pathinfo是什么:pathinfo不是nginx的功能,pathinfo是php的功能。
php中有两个pathinfo,一个是环境变量$_SERVER['PATH_INFO'];另一个是pathinfo函数,pathinfo() 函数以数组的形式返回文件路径的信息;。
nginx能做的只是对$_SERVER['PATH_INFO]值的设置。

php中的pathinfo()
pathinfo()函数可以对输入的路径进行判断,以数组的形式返回文件路径的信息,数组包含以下元素。
  ● [dirname]  路径的目录
  ● [basename] 带后缀 文件名
  ● [extension]  文件后缀
  ● [filename]  不带后缀文件名(需php5.2以上版本)
例如
[php]
<?php
print_r(pathinfo("/nginx/test.txt"));
?>
[/php]
输出
PHP
1234567 Array(    [dirname] => /nginx    [basename] => test.txt    [extension] => txt    [filename] => test)


php中的$_SERVER[&#39;PATH_INFO&#39;]
PHP中的全局变量$_SERVER[&#39;PATH_INFO&#39;],PATH_INFO是一个CGI 1.1的标准,经常用来做为传参载体。
被很多系统用来优化url路径格式,最著名的如THINKPHP框架。
对于下面这个网址:
http://www.test.cn/index.php/test/my.html?c=index&m=search
我们可以得到 $_SERVER[&#39;PATH_INFO&#39;] = ‘/test/my.html’,而此时 $_SERVER[&#39;QUERY_STRING&#39;] = &#39;c=index&m=search&#39;;
如果不借助高级方法,php中http://www.test.com/index.php?type=search 这样的URL很常见,大多数人可能会觉得不太美观而且对于搜索引擎也是非常不友好的(实际上有没有影响未知),因为现在的搜索引擎已经很智能了,可以收入带参数的后缀网页,不过大家出于整洁的考虑还是想希望能够重写URL
