How to connect to Postgresql in php?

Question

PostgreSQL

As a result of the execution

$db = pg_connect("/* параметры для подключения */");

$stat = pg_connection_status($db);
if ($stat === PGSQL_CONNECTION_OK) {
  echo 'Статус соединения: доступно';
} else {
  echo 'Статус соединения: разорвано';
}

I get
PHP Warning: pg_connect(): Unable to connect to PostgreSQL server: SSL error: wrong version number expected authentication request from server, but received S in /test.php
on line can't solve the problem :(
