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 |
