echo json_encode($person);
?>
$person = array("Name"=>'Konok', "Age"=>25, "Country"=>'Bangladesh');
echo json_encode($person);
?>
The result will be : {"Name":"Konok","Age":25,"Country":"Bangladesh"}

var_dump(json_decode($person));
?>
The result will be : object(stdClass)#1 (3) { ["Name"]=> string(5) "Konok" ["Age"]=> int(25) ["Country"]=> string(10) "Bangladesh" }
