PHP实现的激活用户注册验证邮箱功能示例

include_once("connect.php");//连接数据库
$verify = stripslashes(trim($_GET['verify']));
$nowtime = time();
$query = mysql_query("select id,token_exptime from t_user where status='0' and
`token`='$verify'");
$row = mysql_fetch_array($query);
if($row){
  if($nowtime>$row['token_exptime']){ //24hour
    $msg = '您的激活有效期已过，请登录您的帐号重新发送激活邮件.';
  }else{
    mysql_query("update t_user set status=1 where id=".$row['id']);
    if(mysql_affected_rows($link)!=1) die(0);
    $msg = '激活成功！';
  }
}else{
  $msg = 'error.';
}
echo $msg;
