PHP的COOKIE在设定之后,必须要刷新一下网页才能生效,至于是什么原因,有人说是为了安全考虑,至于你信不信,反正我信了

不过,这种机制总是会给我们带来这或那的问题,比如前段时间,我的站点上得设置一个广告显示的功能,就需要用到COOKIE,主要目的是为了加大广告的转化率,可是如果刷新生效,就比较麻烦,所以就用了这种方法,好用。
下面是代码:
代码如下:
function cookie($var, $value='', $time=0, $path='', $domain=''){
$_COOKIE[$var] = $value;
if(is_array($value)){
foreach($value as $k=>$v){
setcookie($var.'['.$k.']', $v, $time, $path, $domain, $s);
}
}else{
setcookie($var, $value, $time, $path, $domain, $s);
}
}

//调用方法

cookie("website","WEB开发笔记","./","www.jb51.net");
//
echo $_COOKIE["website"];//输出WEB开发笔记
