Question

解决了问题。谢谢大家。

代码：

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "SELECT * FROM movie WHERE status = 'In Cinemas' LIMIT 6";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {

$moviename = $row['moviename'];
$cover = $row['poster'];

header('Content-Type: application/json; charset=utf-8');

$alldata [] = array('key'=>'movie-name', 'value'=>$moviename,'cover' =>$cover);
echo json_encode($alldata);

}}
else{

echo "does not work";
}

结果：

    { "items": 
[ 

{"key":"movie-name","value":"test","cover":"upload/movies/poster/1.png"}

{"key":"movie-name","value":"London","cover":"upload/movies/poster/2.png"}

]}

问题：

没有逗号分隔json的两个输出，以{“key”开头 - 括号之前应该是逗号，请帮助实现

解决了问题。谢谢大家。

Answer 1

$sql = "SELECT * FROM movie WHERE status = 'In Cinemas' LIMIT 6";
$result = $conn->query($sql);
$master_array = array();

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
$moviename = $row['moviename']; 
$poster = $row['poster'];

$master_array[] = array('key'=>'movie-name','value'=>$moviename,'cover'=>$poster);

}
header('Content-Type: application/json; charset=utf-8');
    echo json_encode($master_array);

}
else{

echo "no";
}

json - 用逗号循环
