Question

I want to create JSON object using tow query in PHP , Then retrieve this object using ajax . where the first one will return all users . the second nested query will return all tasks associated to particular user . The structure must be like this :

{
[
user1 : { "name" : "name1"
          "task" : [ { "taskname":"taskname1.1" , "date":"1-1" } ,

                 { "taskname":"taskname1.2" , "date":"1-1"  }
        }
} ,

user2: { "name" : "name2"
      "task" : [ { "taskname":"taskname2.1" , "date":"2-2" } ,

                 { "taskname":"taskname2.2" , "date":"2-2"  }
               ]
  }
...
]
}

my problem is :

when I try to parse each user’s tasks , I found that :

each user’s tasks are merged with the Previous user(s)’ tasks .

So what is the best way to create JSON object with the same structure of mine using php ?

— update —

Thanks for everyone who answer me . But I need to know how to create this dynamically , I know how to do this in static and I use json_encode() correctly before , this is not my problem . I really appreciate your answers but this is not what I need and I think the problem is in my question .

$array=array(
    'user1'=>array(
                      'tasks'=>array(
                               'task1'=>'whatever',
                               'task2'=>'whatever',
                               'task3'=>'whatever'
                               ),
                      'date'=>'whatever'
                  ),

    'user2'=>array(
                      'tasks'=>array(
                               'task1'=>'whatever',
                               'task2'=>'whatever',
                               'task3'=>'whatever'
                               ),
                      'date'=>'whatever'
                  ),
    'user3'=>array(
                      'tasks'=>array(
                               'task1'=>'whatever',
                               'task2'=>'whatever',
                               'task3'=>'whatever'
                               ),
                      'date'=>'whatever'
                  )    
);

Then use JSON encode to send the JSON string.

echo json_encode($array);
