PDO Last Insert ID

Tried quite a few ways but always returns:

Any ideas?

EDIT
Using MSSQL and mainly getting not supported by driver error.

Is there any way I can incorporate getting the last ID without running a SELECT query?

if(isset($_POST['createpub']))  {
 
//Create publication
  $sth = $dbconn->prepare("INSERT INTO publication (title, text, cat, user_id, use_ad, viewcount, tags) VALUES (:title, :text, :cat, :user_id, :use_ad, :viewcount, :tags)");
  $params = array(
  "title" => $_POST[title],
  "text" => $_POST[description],
  "cat" => $_POST[category],
  "user_id" => $userid,
  "use_ad" => 0,
  "viewcount" => 0,
  "tags" => $_POST[keywords]
  );
  $status = $sth->execute($params);
 
if ($status) {
  //Create folder using insert id
  echo $sth->lastInsertId();
 
  //mkdir("../publication/$userid/$sth->lastInsertId()");
} else {
  //Failed
  //Debug test
  print_r($params);
}

If I'm not mistaken, you should use:

echo $dbconn->lastInsertId();

Tried many different variations. Always end up with unsupported driver error though.

Although the driver I have is MSSQL_70

This should work shouldn't it?
