如何从这里获取地方

Question

我有一个包含地方详细信息的表名app_places see image of my table

问题：我想只获取一次数据并想以json格式显示相同的place_id

这是我的代码：

load

我需要以下输出

$sql="SELECT place_id FROM `app_places` ";
$check= mysqli_query($conn, $sql);
while ($row = mysqli_fetch_array($check,MYSQLI_ASSOC)) {
    $place_id=$row['place_id'];

    $sql1="SELECT * FROM app_places where place_id='".$place_id."' limit 1";
    //var_dump($sql1);
    $check2= mysqli_query($conn, $sql1);
    while($result=mysqli_fetch_array($check2,MYSQLI_ASSOC))
    {
        $json []= $result;
    }

    $json1 []= array("place"=>$json);
}

echo json_encode($json1);

但输出来自于此并非按照我的要求提前谢谢，请帮助我。

Answer 1

$json = array();
$sql = "SELECT description, place_id, image FROM app_places GROUP BY place_id";
$check = mysqli_query($conn, $sql);
while ($result = mysqli_fetch_assoc($check))
{
    $json[] = $result;
}
echo json_encode($json);
