PHP Specify the Return Type Hints for a Method
<p>What is the correct syntax for me to specify the return type hints for a method?</p>

<p>For example, I have such a method:</p>

<pre><code>private static function ConstructPDOObject($dbname) 
{
   $hostname =self::HOSTNAME;
  $username = self::USERNAME;
  $password = self::PASSWORD;
  $dbh = new PDO("mysql:host=$hostname;dbname=$dbname", $username, $password);
  return $dbh;
}
</code></pre>

<p>And I want, whenever I call the above method, the IDE will show me the methods for PDO.</p>

<p>How to add the type hint?</p>
