java组织。json。JSONException:在{main}（）的第6个字符处的main后面应该是“：”
这是我的php代码
<?php
$con= mysqli_connect("localhost","root","123@123","mysql");
$email=$_POST["email"];
$password=$_POST["password"];
$statement = mysqli_prepare($con,"select * from Userdata where email = ? and password = ? ");
mysqli_stmt_bind_param($statement, "ss", $email, $password);
mysqli_stmt_execute($statement);

$user = array();
while(mysqli_stmt_fetch($statement)){
$user[name]= $name;

$user[phone]=$phone;
}
$users = array_values($user);
echo json_encode($user);

我是php新手，对Android有一点了解。我已经完成了这个注册应用程序，数据存储在数据库中，但当我尝试使用相同的详细信息登录时，我收到了这个错误
