How to send message to selected user with their name laravel

I'm trying to send a message to selected users with their names. So let's say I have two users Ethan and Calvin then the message should start like User1:(Hi, Ethan), User2:(Hi, Calvin). So far the message is like (Hi, Ethan,Calvin) for every user. How can I fix this?

Blade

<form  action="" method="POST">
@foreach($users as $user)
<textarea   name="message" ></textarea>
<input type="checkbox" name="phone[]" @if(!old() || old('phone') == 'true')  @endif   value=" 
">
<input type="checkbox" name="name[]" value=""/>
<button type="submit" class="btn btn-primary">
send Message
</button>
@endforeach
</form>

Controller

    public function message(Request $request)
    {
     $message = $request->input('message');
     $postData = $request->all();

     foreach ($postData['phone'] as $index => $value) {
        $postData['phone'][$index] = Str::replaceFirst('1','965',$value);
    }
    foreach($postData['name'] as $index => $names){
        $postData['name'][$index] = $names;
    }
     $phone_number = implode(',', $postData['phone']);
     $name = implode(',', $postData['name']);


     $send_message = new MyHelper();
     $message = "Hi, $name $message";
     $send_message->sendMessage($phone_number,$message);
     return 'success'; 
    }
