这是一个朋友在学php时的一个学习笔记,其功能就是设置cookie然后注销及输出cookie值的具体操作方法。

setcookie() 函数用于设置 cookie。

注释:setcookie() 函数必须位于 标签之前。

语法

setcookie(name, value, expire, path, domain);

下面看实例

 代码如下 复制代码


//注销cookie
if(isset($_GET['out'])){
setcookie('us',"");
echo "<script>location.href='index.php'</script>";
}

//设置cookie
if(isset($_POST['sub'])){
setcookie("us",$_POST['user'],time()+3600);
echo "<script>location.href='index.php'</script>";
}

//输出和注销cookie
if($_COOKIE['us']){
echo $_COOKIE['us'];
echo "注销cookies";
}

?>
