PHP利用缓存处理用户注册时的邮箱验证，成功后用户数据存入数据库操作示例

<?php
header("content-type:text/html;charset=utf-8");
@$atc=$_get['atc'];
$mem=new memcache();
$mem->connect("127.0.0.1","11211");
if($atc=="in"){
  $res=$mem->add("login",$_post,memcache_compressed,0);
  $meil=$mem->get("login");
  $address=$meil['address'];
  include "./phpmailer/mail.class.php";
  $validate=md5(md5("luyaran"));
  $url="http://www.luyaran.com/login.php?atc=jihuo&validate=".urlencode(base64_encode($validate));
  $content="<a href='{$url}'>".$url."</a>";
  if(mail::send($content,$address)){
    echo "<script>alert('注册成功');</script>";
  }else{
    echo "<script>alert('注册失败');</script>";
  }
}else if($atc=="login"){
//登陆时需查看状态码是否激活
 include "table.html";
}else if($atc=="jihuo"){
  //验证用户名和密码是否与缓存中的一致
  include "table.html";
}else{
  include "table2.html";
}
?>
