  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

$result = mysqli_query($con,"SELECT * FROM users");

echo "<table border='1'>

while($row = mysqli_fetch_array($result))
  {

尝试mysqli_fetch_assoc（$result）或mysqli_fetch_数组（$result，MYSQL_assoc）而不是mysqli_fetch_数组（$result）

您的

用户的模式是什么？
$result=mysqli_查询（$con，“从用户中选择*”）或die（mysqli_error（））id、用户名、密码、名称和密码address@dianuj仍然收到相同的错误通知
