Tutorial

First of all, we must get the current page URL. Here we use php$ _SERVER['PHP_SELF']To get the web page address
Assume the url is http://www.php.cn/

$php_Self= $_SERVER['PHP_SELF']; //获取网页地址
//输出结果：http://www.php.cn/

Output Later, we found that we only need index.php, and the previous list of things are useless.

substr syntax
substr(string,start,length)

//获得当前的脚本网址 
function GetCurUrl()

  if(!empty($_SERVER["REQUEST_URI"])) 
  {
    $scriptName = $_SERVER["REQUEST_URI"];
    $nowurl = $scriptName;
  } else 
  {
    $scriptName = $_SERVER["PHP_SELF"];
    if(empty($_SERVER["QUERY_STRING"])) 
    {
      $nowurl = $scriptName;
    } else 
    {
      $nowurl = $scriptName."?".$_SERVER["QUERY_STRING"];
    }
  }
  return $nowurl;
}
