first have format data in structure want in php , @ end have encode json.. might have read data in array , create model classes , encode json

json_encode() 

sample code

$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);  echo json_encode($arr); 

the out put {"a":1,"b":2,"c":3,"d":4,"e":5}
