php - mySQL 获取数据到关联数组

Question

我正在使用以下代码从我的数据库中获取用户列表:

if ($result = mysqli_query($mysqli, "SELECT user_name, name, surname, avatar, user_email FROM users")) {


    while ($row = $result->fetch_assoc()) {
        $username[]  = $row["user_name"];
        $user_email[] = $row["user_email"];
        $user_name[] = $row["name"];
        $user_surname[] = $row["surname"];
        $avatar[] = $row["avatar"];

    }

    $result->close();
}

但是我得到以下错误:

Fatal error: [] operator not supported for strings

Answer 1

这可能是你想要做的:

   $rows = array();
   while ($row = $result->fetch_assoc()) {
       $rows[] = $row;
   }
   // $rows is now an array that contains each individual row from your result set

然后您可以对该数据做任何您想做的事情，例如将其显示在表格中或其他任何地方。

  foreach($rows as $user)
  {
    echo $user['user_name'] . ' - ' . $user['user_email'];
  }

等等
