$sth = $db->prepare("INSERT INTO user (name, email,password)
VALUES(:name,:email,:pass)");
$sth->bindParam(':name', $name, PDO::PARAM_INT);
$sth->bindParam(':email', $email, PDO::PARAM_INT);
$sth->bindParam(':pass', $pass, PDO::PARAM_INT);

);
echo json_encode($output);
$db = null;
return;
}
}
catch(Exception $ex){
echo $ex;
}
});

"unexpected e" happens because Postman was expecting the output to be a JSON response.
When you get the response, click the 'Raw' or 'Preview' tab. Or choose one of the other formats from the drop-down menu. You'll see the rest of the response.
