$url = 'http://'.$_SERVER['HTTP_HOST'].substr($REQUEST_URI,0,strrpos($REQUEST_URI,'/'));

//echo strrpos($REQUEST_URI,'/');
//echo substr($REQUEST_URI,0,strrpos($REQUEST_URI,'/'));
echo dirname($_SERVER['SCRIPT_FILENAME']);

echo $_SERVER['DOCUMENT_ROOT'];
echo "

echo $_SERVER['DOCUMENT_ROOT']."
";?? //獲得伺服器文檔根
echo $_SERVER['PHP_SELF']."
"; //獲得執行該代碼的檔案伺服器絕對路徑
echo __FILE__."
"; //獲得檔案的檔案系統絕對路徑
echo dirname(__FILE__); //獲得檔案所在的檔案夾路徑


結果
