Question

如果你看到我的输出在第一个用户asad ali 2行跟随和图像路径之间的差距，为什么其他用户没有任何差距为什么？我想在第一个用户中删除这个差距，感谢您的帮助只有php编码我正在使用sql查询左表连接在图像表中当用户上传图像数据时保存在数据库图像中，用户ID为＆amp;图像path.if一个用户上传不同的图像然后用户ID重复，所以我想只打印一次用户ID和相同user.same的所有相关图像，如果名称在表中重复，那么我想在输出中打印唯一

我的编码是

    <?php
$conn = mysqli_connect("localhost","root","","discover");
if(isset($_REQUEST['user_id']) && isset($_REQUEST['session_id'])){
    $user_id=$_REQUEST['user_id'];
    $session_id=$_REQUEST['session_id'];
    $sql="SELECT * FROM `users` where user_id='$user_id' AND session_id='$session_id'";
    $result=mysqli_query($conn,$sql);
    if($result->num_rows>0)
    {
    $sqlb="SELECT * FROM `users` LEFT JOIN `followers` ON users.user_id=followers.user_id LEFT JOIN `image` ON users.user_id=image.user_id order by users.user_id asc";
$resultb=mysqli_query($conn,$sqlb);
if($resultb->num_rows>0)
 {
    $i=0;
    $user_id=array();
    $result=array();
    // $user_name=array();
    // $user_pic_path=array();
while ($rowb = $resultb->fetch_assoc()) 
{   
    var_dump($rowb);
    $userid = $rowb['user_id'];
    $user_name = $rowb['fast_name']." ".$rowb['last_name'];
    $user_pic_path=$rowb['user_pic_path'];
    $user_follow=$rowb['follower_id'];

    if($user_follow == $user_id)
    {
        $user_followi = TRUE;
    }
    elseif($user_follow !== $user_id)
    {
        $user_followi = FALSE;
    }
    if(!isset($result[$userid]))
    {
        $result[] = array('user_name'=>$user_name,'user_profile_pic'=>$user_pic_path,'follow'=>$user_followi);
    }
    $result[$userid]['image_path'][] = $rowb['image_path'];
}
$response['session']=TRUE;
$response['status']=TRUE;
$response['msg']="user data find successfully";
$response['user_detail']=$result;
echo json_encode($response);
}
 }
 else
    {
        $response['session']=TRUE;
        $response['status']=FALSE;
        $response['msg']="wrong data enter";
        echo json_encode($response);
    }           
}
else
    {
    $response['session']=FALSE;
    $response['status']=FALSE;
    $response['msg']="user does not exists";
    echo json_encode($response);
    }
?>

我的输出是

    // 20180103125211
// http://localhost/1111.php?user_id=2&session_id=953455543

    }
  ]
}

除了一个原因外，json编码对所有数组输出相同
