fist of all creat a multidimensioal array to respresent that then encode it to json format.like this:

$array = array(
 'product'=>array(
    'mainid'=>1,
     "productinfo"=>array(
       0=>array('subid'=>1222 ,'rate'=>4),
       1=>array("subid"=>"1222",
        "rate"=>"74")
        //and so on
     ) 
  ),
);

then you encode it into josn using:

json_encode($array);

@sasikumar oooh man this can not be done via a question,you need to know database(like mysql) ,php ,PDO and...this is a mini project it self.you asked how to create json

@sasikumar ok.you have a database ant it has a product table. using PDO (this is what i recommend) create a connection to database in your php script then it returns a set of products.use foreach to go throgh each of results and store each row wanted fields in a multi dimensioal array and then produce json.i hope i could have helped you to gain an overall guid.good luck

$make=array();
$vtype=array();
$index = array(
   'make'=>$make,
   'vtype'=>$vtype,
);
