Description:
------------
I am using a base class and a lot of classes which extend that base class. When i add class variables in the base class i can use those in the extending class. All goed well. But when i set variables from the base class constructor then the extended class does not get these new values. I tested, and the base class constructor is not executed.

Reproduce code:
---------------
class base {
    var $mysql_link = null;
    var $test = "hello";

    function base() {
      $this->test = "helloolleh";
      $this->mysql_link = mysql_connect("host", "user", "pass");
      if(!$this->mysql_link)
        exit("mysql connection failed.");
    }
}

class photo extends base {
      photo() {
        print "photo constructor is working!\n";
        print "But the base class not: '".$this->test."'\n";
        mysql_query("Select foo from bar", $this->mysql_link) or die(mysql_error());
      }
}

$p = new photo();

Expected result:
----------------
photo constructor is working!
helloolleh
Error in query

Actual result:
--------------
 // nothing
hello
mysql: not a valid resource identifier
