php 简单的cookie问题~~
做一个简单的网站登录界面和登出界面,在登入界面的php代码中设置了cookie,想在这个程序中显示出来却显示不出来,在登出界面的代码中就可以显示出来。
登入代码中设置和显示cookie的代码如下
<br /> //设置本机Cookie信息<br /> $set_info = $record[1]."|".$record[3]; //record是从数据库中查询的结果,这是没有问题的<br /> setcookie("userinfo", $set_info, time()+60*60*24); //设置本机cookie<br /> //从Cookie中提取信息<br /> $pp = explode("|", $_COOKIE[userinfo]); //从cookie中把两条信息分割分别提取<br /> echo $pp[0]."----".$pp[1]."<br>"; //输出这些信息。问题就出现在这!打印出来的东西是空的,什么都没有,上一行的userinfo加不加双引号单引号都一样。<br />
但是在登出界面的代码中就能显示出来
<br /> //读取Cookie中的信息<br /> echo "以下是Cookie变量的内容:<br>";<br /> $pp = explode("|", $_COOKIE["userinfo"]);<br /> echo $pp[0]."----".$pp[1]."<br>"; //这里可以很正常的显示出来!!!!<br /> //释放Cookie变量<br /> setcookie("userinfo", "");<br />
这是为什么阿!!!难道是cookie还有其他的什么机制么?在登录的时候显示不出来?求解答!
