Question

我在桌子上有泰米尔语文本，而我使用PHP检索数据我得到了???作为回应。

以下是我的PHP代码。

    <?php 
header( 'Content-Type: text/html; charset=utf-8' );
include('connection.php');

$query = "SELECT * FROM DevotionalCollection";
$fetch=mysqli_query($con, $query ) or die(mysqli_error($con));

if (mysqli_num_rows($fetch) > 0) {
    $response["data"] = array();
    while ($row = mysqli_fetch_array($fetch)) {

        $data = array();
        $data["playlistname"] = $row["playlistname"];
        $data["playlistid"] = $row["playlistid"];
        $data["channelname"] = $row["channelname"];
        $data["imageURL"] = $row["imageURL"];

        //$response["data"] = array();
        array_push($response["data"], $data);

    }
    header('Content-type: text/json');
    $response["success"] = TRUE;
    // echoing JSON response
    echo json_encode($response);
}else {
    // no products found
    $response["success"] = FALSE;
    $response["message"] = "No data found";

    // echo no users JSON
    echo json_encode($response);
}

?>

检查连接中的字符集:(首选将其放在connection.php中）

header( 'Content-Type: text/html; charset=utf-8' );
include('connection.php');

// Change character set to utf8
mysqli_set_charset($con,"utf8");

$query = "SELECT * FROM DevotionalCollection";
$fetch=mysqli_query($con, $query ) or die(mysqli_error($con));

if (mysqli_num_rows($fetch) > 0) {
    $response["data"] = array();
    while ($row = mysqli_fetch_array($fetch)) {

        $data = array();
        $data["playlistname"] = $row["playlistname"];
        $data["playlistid"] = $row["playlistid"];
        $data["channelname"] = $row["channelname"];
        $data["imageURL"] = $row["imageURL"];

        //$response["data"] = array();
        array_push($response["data"], $data);

    }
    header('Content-type: text/json');
    $response["success"] = TRUE;
    // echoing JSON response
    echo json_encode($response);
}else {
    // no products found
    $response["success"] = FALSE;
    $response["message"] = "No data found";

    // echo no users JSON
    echo json_encode($response);
}

?>

更改数据库中的字符集：

ALTER DATABASE DBNAME CHARACTER SET utf8 COLLATE utf8_general_ci;

得到????标记为来自php的响应，而不是获取泰米尔语文本字符串。
