In the standard mode of the Language Bindings, a database command can be sent to the server using the execute() function of the Session. This functions returns the whole result. With the info() function, you can request some information on your executed process. If an error occurs, an exception with the error message will be thrown.


The standard execution works as follows:

  1. Create a new session instance with hostname, port, username and password.
  2. Call the execute() function of the session with the database commands as argument.
  3. Receive the result of a successfully executed command. If an error occurs, an exception is thrown.
  4. Optionally, call info() to get some process information
  5. Continue using the client (back to 2.), or close the session.

try {
  // initialize timer
  $start = microtime(true);

  // create session
  $session = new Session("localhost", 1984, "admin", "admin");
  // perform command and print returned string
  print $session->execute("xquery 1 to 10");

  // close session

  // print time needed
  $time = (microtime(true) - $start) * 1000;
  print "\n$time ms\n";

} catch (Exception $e) {
  // print exception
  print $e->getMessage();
