複製代碼 代碼如下:function getsiteurl()
{
global $_SCONFIG;
if(empty($_SCONFIG['siteallurl']))
{
$uri = $_SERVER['REQUEST_URI']?$_SERVER['REQUEST_URI']:($_SERVER['PHP_SELF']?$_SERVER['PHP_SELF']:$_SERVER['SCRIPT_NAME']);
return shtmlspecialchars('http://'.$_SERVER['HTTP_HOST'].substr($uri, 0, strrpos($uri, '/')+1));
}
else
{
return $_SCONFIG['siteallurl'];
}
}
global $_SCONFIG; //定義全域變數$_SCONFIG($_SCONFIG其實是個數組var,在common.php中有定義)
if(empty($_SCONFIG['siteallurl'])) //判斷$_SCONFIG['siteallurl']變數是否為空白
$uri = $_SERVER['REQUEST_URI']?$_SERVER['REQUEST_URI']:($_SERVER['PHP_SELF']?$_SERVER['PHP_SELF']:$_SERVER['SCRIPT_NAME']);
//將$_SERVER['REQUEST_URI'];$_SERVER['PHP_SELF'];$_SERVER['SCRIPT_NAME']通過三目運算後把結果給$url
//$_SERVER也是數組,你可以列印一下,就知道幹嗎用的了.這裡只涉及到三個數組元素
//$_SERVER['REQUEST_URI']; //REQUEST_URI:/mysite/->網站目錄?
//$_SERVER['PHP_SELF']; //PHP_SELF:/mysite/index.php->當前正在執行指令碼的檔案名稱
//$_SERVER['SCRIPT_NAME']; //SCRIPT_NAME:/mysite/index.php->包含當前指令碼的路徑
