//获取全部URL                                                                                         
$url='http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
//获取不包含参数的URL
$url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["PHP_SELF"];
//获取地址
$url=$_SERVER['PHP_SELF'];
//获取路径
$url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"];
//获取指定的参数比如url为:http//www.pengyaou.com/Test.php?Name=neo&Year=20&Hobby=123456
$name=$_REQUEST['Name'];
$year=$_REQUEST['Year'];
$hobby=$_REQUEST['Hobby'];
