php $_COOKIE简单应用实例
COOKIE 是在网页内容发送之前。先发送出去的信息。也就是说。在这之前不能有任何的 HTML 代码和 echo 等,即使是一个空格也是不允许的。。

在php教程中,要用 setcookie 函数来注册 cookie 变量,你上面的代码没有注册 cookie 变量。怎么可能送得过去呢。正确的写法如下:
*/
$status=0; //定义状态
if(isset($_cookie['mytstcky'])&&($_cookie['mytstcky']=="chocchip")) $status=1; //如果已经设置变量
if(!isset($_get['cchk'])) //如果没有设置变量
{
setcookie("mytstcky","chocchip"); //发送cookie信息
header("location:$php_self?cchk=1"); //发送标头
exit; //结束php代码
}
?>
cookie check status:
printf('%s
;',$status ? "00ff00" : "ff0000",$status ? "passed!" : "failed!"); //根据条件输出不同内容
?>
