please i've asked earlier , wasnt including details time ive included whole sample when included apart console gives no error. thank `

you should add following header php file:

header('content-type: text/json'); 

besides that, put data directly array , use json_encode. php file should this:

<?php header('content-type: text/json'); $results = array( "item1"=> "i love jquery4u", "item2"=> "you love jquery4u", "item3"=> "we love jquery4u" ); echo json_encode($results); ?> 

which give following result:

{     "item1": "i love jquery4u",     "item2": "you love jquery4u",     "item3": "we love jquery4u" }
