Question

对不起......！我的英文不是很好！直到上周我使用“www.000webhost.com”webhost，我没有问题！但是今天我买了一台新服务器并像以前一样使用旧文件...... 我不知道问题是来自php文件还是数据库？

请告诉我解决方案

这是我的PHP代码

    <?php 
    //Creating a connection
    $con = mysqli_connect("___","___","___","___");

    if (mysqli_connect_errno())
    {
       echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }
    /*Get the id of the last visible item in the RecyclerView from the request and store it in a variable. For            the first request id will be zero.*/  
    $id = $_GET["id"];

    $sql= "Select * from db_app where id between ($id+1) and ($id+10)";

    $result = mysqli_query($con ,$sql);

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

        $array[] = $row;

    }
    header('Content-Type:Application/json');

    echo json_encode($array);

    mysqli_free_result($result);

    mysqli_close($con);

 ?>

这是我的数据库代码

    CREATE DATABASE `android_db`;

USE `android_db`;


CREATE TABLE IF NOT EXISTS `db_app` (
  `id` int(15) NOT NULL AUTO_INCREMENT,
  `movie_name` varchar(45) NOT NULL,
  `movie_image` varchar(10000) NOT NULL,
  `movie_genre` varchar(40) NOT NULL,
  PRIMARY KEY (`id`)
);

未设置字符集时会发生这种情况。

尝试mysql连接后，

/* change character set to utf8 */
if (!$mysqli->set_charset("utf8")) {
    printf("Error loading character set utf8: %s\n", $mysqli->error);
    exit();
} else {
    printf("Current character set: %s\n", $mysqli->character_set_name());
}

取自：http://php.net/manual/en/mysqli.set-charset.php

问号显示像“????”而不是来自php或mysql的波斯人物......！
