Q:

PHP Get multiple data from mysql in array

I am trying to get multiple columns data in a array fromate form data base like for example
[{"id":"3","category":"Name","text":"text with some data","image":"http:\/\/examole.net\/folder\/images\/category1.jpg"},{"id":"4","category":"Name","text":"text with some data","image":"http:\/\/examole.net\/folder\/images\/category1.jpg"}]

using for each statement i am not able to do it as a json response
$response = array();
if(isset($_REQUEST['action']) && $_REQUEST['action']=='test'){
        $query="select * from exampledb where id='".$db->escape($_REQUEST['id'])."'"; 
        $num= $db->num_rows($query);          
        if($num)
        {
            $rows = $db->get_results($query);

            foreach($rows as $row1) { 

                $response['id'] = $row1['id'];
                $response['category'] = $row1['category'];
                $response['text'] = $row1['text'];
                $response['image'] = $row1['image'];
            }       
        }
        else{
            $response['message']='No user Found';
            $response['status']='fail';
        }

    }

A:

after your else
else{
            $response['message']='No user Found';
            $response['status']='fail';
        }

echo json_encode($response) //<---- here convert array to json text

PHP json_encode
UPDATE
foreach($rows as $k=>$row1) { //add index $k to use an automatic autoincrement for the key
//and put it inside each fields
                $response[$k]['id'] = $row1['id'];
                $response[$k]['category'][] = $row1['category'];
                $response[$k]['text'] = $row1['text'];
                $response[$k]['image'] = $row1['image'];
            }
