php - ajax response returns [object] using pdo and show my query -

getting querystring sent ajax response. ajax works know id being passed , have echo variable in php , show correct when use json encode [object] alert in , response looks

response:

{"querystring":"select * contactinfo id = :id"} 

php:

$id = $_post['id']; if (empty($id)) {     echo "no id"; } try {     $conn = new pdo('mysql:host=localhost;dbname=test;charset=utf8', user, pass);     $conn->setattribute(pdo::attr_errmode, pdo::errmode_exception);        $stmt = $conn->prepare('select * contactinfo id = :id');     $stmt->execute(array('id' => $id));     echo json_encode( $stmt);     } catch(pdoexception $e) {         echo 'error: ' . $e->getmessage();     } 

js:

    $.ajax({         type: "post",         timeout: 6000,         data : {id: myid}, // add if using post         datatype : 'json', //text         crossdomain: false,         cache: false,         async: true,         url: requrl,         success: function(data) {             alert(data);                                 } 

you need pass result array use fetch():

$result = $stmt->fetch(pdo::fetch_assoc); echo json_encode( $result ); 

then jquery return object here's how can access it:

success: function(data) {               alert(data.firstname);  } 

edit: noticed you're returning 1 row it's not fetchall().
