使Nginx支持PATH_INFO

在fastcgi_params文件中加入以下内容

set $path_info "";
set $script_name $fastcgi_script_name;
if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
 set $script_name $1;
 set $path_info $2;
}

fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
fastcgi_param SCRIPT_NAME $script_name;
fastcgi_param PATH_INFO $path_info;
