PHP 代码是这样的，文件名是：get_users.php
- <?php
- /*
- $page = isset($_POST['page']) ? intval($_POST['page']) : 1;
- $rows = isset($_POST['rows']) ? intval($_POST['rows']) : 10;
- $offset = ($page-1)*$rows;
- */
- //include 'conn.php';
- $servername = "127.0.0.1";
- $username = "root";
- $password = "12345678";
- // 创建连接
- $conn = new mysqli($servername,$username,$password);
- // 验证连接
- if (!$conn) {
- die('连接失败！！！' . $conn->connect_error);
- }
- echo "连接成功<br>";
- mysqli_query($conn , "set names utf8");
- $tb_coon = mysqli_select_db($conn,'mydb');
-
- $rs = mysqli_query($conn,"select * from users");
- $result = array();
- /*
- $row = mysqli_fetch_row($rs);
- $result["total"] = $row[0];
- $rs = mysqli_query($conn,"select * from users limit $offset,$rows");
- $items = array();
- while($row = mysqli_fetch_object($rs)){
- array_push($items, $row);
- }
- $result["rows"] = $items;
- */
- while($row = mysqli_fetch_object($rs)){
- array_push($result, $row);
- }
- echo json_encode($result);
- /*
- $rs->free();
- $mysql->closedir;
- */
- ?>
内容就是不显示出来，找了很多网上，方法都用到了,我把文件都放在同一个目录下。求大神帮忙 |
