Php 由于某种原因，这一错误和胜利'；我不能注册我的用户 $encrypt1=hash（'sha512'，$password）； $encrypt=hash（'sha512'，$encrypt1）； 会话_start（）； $\会话['username']=$user； $\会话['password']=$encrypt； $ip=$\u服务器['REMOTE\u ADDR']； $data1=“在用户中插入用户名、密码、电子邮件、ip值：用户名、密码、电子邮件、ip”； $data2=$handler->prepare（$data1）； $data2->execute（数组（':username'=>$username'，：password'=>$encrypt'，：email'=>$email'，：ip'=>$ip））； echo“您已成功注册-立即重定向”； 标题（'Refresh:5；URL=../'）；

我相信错误就在这段代码的某个地方

我想我在prepare或execute语句中出错了

INSERT

需要在列和值列表周围加括号：

$encrypt1 = hash('sha512',$password);
$encrypt = hash('sha512',$encrypt1);
session_start();
$_SESSION['username'] = $user;
$_SESSION['password'] = $encrypt;
$ip = $_SERVER['REMOTE_ADDR'];
$data1 = "INSERT INTO users username, password, email, ip VALUES :username,:password,:email,:ip";
$data2 = $handler->prepare($data1);
$data2->execute(array(':username' => $username, ':password' => $encrypt, ':email' => $email, ':ip' => $ip));
echo "<div class='reg-success'><p class='basic-font reg-success-txt'>You         have been successfully registered - Redirecting Momentarily</p></div>";
header('Refresh: 5; URL=../');

这一行：

$data1 = "INSERT INTO users (username, password, email, ip)
          VALUES (:username,:password,:email,:ip)";

应该是：

$data1 = "INSERT INTO users username, password, email, ip  
          VALUES :username,:password,:email,:ip";

$data1
