Cookie Usage_PHP Tutorial

Cookie Usage Today we will take a look at the php cookie usage and give a simple example to illustrate. I don’t think most people will understand the cookie. It just saves a cookie file on the client. Use a browser to read it, so I won’t say much else. If you want to know more, please go to www.111cn.cn.

$value =$_SERVER['HTTP_HOST'];
echo $value;
if(empty($_COOKIE["cook"])){
setcookie("cook", $value, time()+1800, "/");
if(sizeof($_POST)<8){echo 'bb';}
for($i=1;$i<=8;$i++){
$c =$_POST['r'.$i];
switch( intval($c) ){
case 0:
       $word ='vote_r1';
        break;
case 1:
        $word ='vote_r2';
        break;
Case 2:
        $word ='vote_r3';
        break;
​​default:
exit('error');
}
$sql="update gx_votes set $word=$word+1 where id=$i";
Mysql_query($sql) or die(mysql_error());
}
echo 'os';
}else{
print '00';
}
