[Nginx] Nginx配置PHP应用传递PATH_INFO变量

这里比较兼容的处理是:

server {
        listen       80;
        server_name  域名;
        root   路径;
        if (!-e $request_filename) {
                rewrite ^/(.*)$ /index.php/$1 last;
                break;
        }
        access_log  /var/log/nginx/域名-access.log;
        error_log  /var/log/nginx/域名-error.log;
        location / {
            index  index.php;
        }

        location ~ .php {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_read_timeout        60s;
            fastcgi_split_path_info  ^((?U).+.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;
        }
} 

这里是非贪婪模式:

fastcgi_split_path_info  ^((?U).+.php)(/?.+)$;

(?U)表示对后面的子串进行非贪婪匹配

fastcgi_split_path_info  ^(.+.php)(/.*)$; 这种是贪婪匹配,具体区别看下图

非贪婪下,只匹配到第一个.php

贪婪下匹配到最后一个.php
