Get all messages from array - php - php

Question

I want to get all messages and put it all into array , but there is another way i want sort all messages by id , for example:
my json :
{"msg_c":[{"message":"Hi","sender":"2","receve":"3","name":"Muhamad Bagzada"},{"message":"Hello","sender":"3","receve":"2","name":"Danyal Join"},{"message":"What's up , How are you ?","sender":"2","receve":"3","name":"Muhamad Bagzada"},{"message":"fine and you ?","sender":"3","receve":"2","name":"Danyal Join"},{"message":"fine","sender":"2","receve":"3","name":"Muhamad Bagzada"}]}
Exactly i want :
show messgaes in array by different value , ( message_u : my msg , messages_m : his msg)
{
"msg_c":
[
{"message_u":"Hi","sender":"2","receve":"3","name":"Muhamad Bagzada"},
{"message_m":"Hello","sender":"3","receve":"2","name":"Danyal Join"},
{"message_u":"What's up , How are you ?","sender":"2","receve":"3","name":"Muhamad Bagzada"},
{"message_m":"fine and you ?","sender":"3","receve":"2","name":"Danyal Join"},
{"message_m":"fine","sender":"2","receve":"3","name":"Muhamad Bagzada"}
]
}
php function :
public function MessageApp ($user_id,$sender){
$data ='';
$Messg = mysqli_query($this->_join, "SELECT * FROM `messages` WHERE (`from` = '$sender' AND `to` = '$user_id') OR (`from` = '$user_id' AND `to` = '$sender') ORDER BY dates ASC LIMIT 12 ");
while ($m = mysqli_fetch_assoc($Messg)) {
$from = $m['from'];
$to = $m['to'];
$chat = $m['chat'];
$dates = $m['dates'];
$id = $m['id'];
if ($user_id === $sender) {
$select_id = $to;
}else{
$select_id = $from;
}
$user = new user($from);
$fullname = ($user->data()->fname)." ".($user->data()->lname);
$gettype['msg_c'][] = array(
'message' => $chat,
'sender' => $from,
'receve' => $to,
'name'=>$fullname
);
$data = json_encode($gettype);
}
return json_encode($gettype);
}
I called json data here :
<?php
include $_SERVER['DOCUMENT_ROOT']."/php/core/init.php";
include $_SERVER['DOCUMENT_ROOT']."/php/core/connect.php";
$my_id = input::get('user_id');
$user = new user($my_id);
$sender = $user->data()->id;
$db = db::getInstance();
$message = new message();
$id = input::get("id");
$user = new user($id);
$user_id = $user->data()->id;
echo $message->MessageApp($user_id,$sender);
?>

When you building the row in msg_c, you can separate the set key in different situation like this
<?php
$msg_row = array(
'sender' => $from,
'receve' => $to,
'name'=> $fullname
);
if ($user_id === $sender) {
$msg_row['message_m'] = $chat;
} else {
$msg_row['message_u'] = $chat;
}
$gettype['msg_c'][] = $msg_row;
Or even build the array in the if else statement before to reuse the code
