在php获取一个url地址我会使用到超级全局变量$_SERVER,他包括了各种参数获取,如HTTP_HOST、PHP_SELF、QUERY_STRING等等,这里就不介绍了。

PHP获取URL的几个函数介绍

 代码如下 复制代码

//获取域名或主机地址
echo $_SERVER['HTTP_HOST']."
";
//获取网页地址
echo $_SERVER['PHP_SELF']."
";
//获取网址参数
echo $_SERVER["QUERY_STRING"]."
";
//来源网页的详细地址
echo $_SERVER['HTTP_REFERER']."
";
?>

把上面的几个函数组合一下,即可得到完整的URL地址

 代码如下 复制代码

// 说明:获取完整URL

function curPageURL()
{
    $pageURL = 'http';

    if ($_SERVER["HTTPS"] == "on")
    {
        $pageURL .= "s";
    }
    $pageURL .= "://";

    if ($_SERVER["SERVER_PORT"] != "80")
    {
        $pageURL .= $_SERVER["SERVER_NAME"] . ":" . $_SERVER["SERVER_PORT"] . $_SERVER["REQUEST_URI"];
    }
    else
    {
        $pageURL .= $_SERVER["SERVER_NAME"] . $_SERVER["REQUEST_URI"];
    }
    return $pageURL;
}
?>

定义该函数之后就可以直接调用了:

 代码如下 复制代码

  echo curPageURL();
?>
