calling inherited function from constructor

[Anon]

Hello:

Does anyone know how the :: is used in pd_entity::pd_entity($name, $info), for example?

The constructor is called from a member function like this:

$functions[$current_function] = new pd_function($name, $info, $current_class);

class pd_function extends pd_entity
{
var $classOf;
var $params = array();
var $ret = "";

function pd_function($name, $info, $classname="")
{

Problem ----->>> pd_entity::pd_entity($name, $info);

	if (count($ret = $info['@return'][""]))
		$this->ret = join(" ", $ret);
	$this->classOf = $classname;
}
