如何将域名后的所有内容转换为字符串 [英] How to get everything after the domain name into a string

问题描述

我的目标是将域名后的所有内容都转换为字符串.如在mysite.com/page/page2中那样，将导致字符串"page/page2".我可以这样做，但是，例如，当站点在子文件夹中而不是在根目录中时，它开始给我带来问题，然后该站点所在的文件夹也将包含在字符串中，并且如果我不使用mod_rewrite来获得漂亮的链接，它还将在字符串中添加index.php.

My goal is to get everything after the domain name into a string. As in mysite.com/page/page2 would result in a string "page/page2". That I can do, however it starts giving me problems when, for example, the site is in a subfolder and not in root, then the folder the site is in will also be included in the string and if I'm not using mod_rewrite to get pretty links, it will also add index.php to the string.

因此，我需要一两个技巧，以使脚本了解网站是否位于子文件夹(如mysite.com/sitefolder/page/page2)中，并且仍然会导致字符串

So, I would need a trick or two to make the script understand whether or not the site is in a subfolder such as mysite.com/sitefolder/page/page2 and that it would still result in a string

page/page2

如果该站点不使用mod_rewrite并且url为mysite.com/sitefolder/index.php/page/page2，则仍然会产生字符串

If the site doesn not use mod_rewrite and the url is mysite.com/sitefolder/index.php/page/page2, it would still result in a string

page/page2

请记住，我在配置文件中定义了URL和USE_MOD_REWRITE，因此不需要魔术.我只是不知道如何去获得那个字符串.我知道我可以做$ _SERVER ['REQUEST_URI']来获取字符串，但是index.php仍然在其中.很抱歉，如果我的解释不够好，但是所有帮助我们都将受到感激.

Keep in mind that I have URL and USE_MOD_REWRITE defined in a config file, so no need for magic. I just have no idea how to go about getting that string. I know I could do $_SERVER['REQUEST_URI'] to get the string, but then index.php would still be in it. I'm sorry if I didn't explain well enough, but all help is appreciated.

推荐答案

• 通过解析请求uri获取路径
• 从字符串末尾删除最终的脚本名称(例如index.php)

• 对所有斜杠进行斜线修饰

  • get the path by parsing the request uri
  • remove eventual script name from the end of the string (e.g. index.php)

  • rtrim any trailing slashes

    
    $request = parse_url($_SERVER['REQUEST_URI']);
    $path = $request["path"];
    $result = rtrim(str_replace(basename($_SERVER['SCRIPT_NAME']), '', $path), '/');
    

  编辑

  $request = parse_url($_SERVER['REQUEST_URI']);
  $path = $request["path"];
  
  $result = trim(str_replace(basename($_SERVER['SCRIPT_NAME']), '', $path), '/');
  
  $result = explode('/', $result);
  $max_level = 2;
  while ($max_level < count($result)) {
      unset($result[0]);
  }
  $result = '/'.implode('/', $result);
