没有真正的知识，赌博仍然存在&问题出现了
我找到一个剧本 m able to tag people but I don 我不知道如何从数据库中检索列表？？？

<?php

  $term = isset($_GET['term']) ? $_GET['term'] : '';

  //TODO: you should retrieve this list from database

  //list of users

  $allUsers = array(
array('id' => 10 , 'title' => ' molendijk '),
array('id' => 20 , 'title' => ' rotterdam '),

    );

    $users = array();
    foreach ($allUsers as $user)
    {
if (stripos($user['title'], $term ) !== false) {
    $users[] = $user;
}
    }

    //generate output
    echo json_encode($users);

    ?>

在//todo:您应该从数据库中检索这个列表，我试图用简单的代码来完成这个列表，但它不起作用

<?php
 // connect to the "tests" database
 $conn = new mysqli('127.0.0.1', 'comments', '123456', 'comments');
 // check connection
 if (mysqli_connect_errno()) {
 exit('Connect failed: '. mysqli_connect_error());
  }
  // SELECT sql query
  $sql = "SELECT * FROM `user`  ORDER BY `id` DESC"; 
   // perform the query and store the result
   $result = $conn->query($sql);
   // if the $result contains at least one row
   if ($result->num_rows > 0) {
    // output data of each row from $result
    while($row = $result->fetch_assoc()) {

//我试图添加$行的用户列表

$allUsers = array(
array('id' => '. $row['id']. ' , 'title' => ' '. $row['user']. ' '),
array('id' => '. $row['id']. ' , 'title' => ' '. $row['user']. ' '),

我希望有人能给我一些建议
