PHP_SELF返回/index.php/index.php

为什么$_SERVER [‘PHP_SELF’]会返回/index.PHP/index.PHP ??

请求

http://example.com

产量

/index.PHP/index.PHP

的index.PHP

<?PHP
echo $_SERVER['PHP_SELF'];

Nginx.conf

server {
    listen  80;
    server_name  domain.com;

    root  /var/www/public/www;

    # Add trailing slash
    rewrite  ^([^.\?]*[^/])$$1/ permanent;

    location / {
        try_files  $uri $uri/ /index.PHP?$query_string;
    }

    location ~ \.PHP${
        include  /var/ini/Nginx/fastcgi.conf;
        fastcgi_pass  PHP;
        fastcgi_param  SCRIPT_FILENAME /var/www/public/www/index.PHP;
    }
}

fastcgi.conf

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  PATH_INFO          $fastcgi_script_name;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    Nginx/$Nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

解决方法:

当使用带有PHP-fpm的Nginx时,这是一个已知问题(链接here)：

When setting SCRIPT_NAME to something, $_SERVER[‘PHP_SELF’] will contain
PHP_SELF environment value concatenated with environment value of SCRIPT_NAME.
