	       type int
	       member int

       The  partition  descriptor  returned by class_open().  Name of the class to which the new member is to be added.  Member type as defined in
       <sys/class.h>.  For example: CL_TYPE_UID.  Identifier representing type.  TRUE/FALSE - If a member is found in  another	class,	force  the
       member to be moved to class_name

RETURN VALUES

       Operation  successfully	completed.  An invalid partition handle was specified.	Not super user.  Permission denied.  The class_name is not
       an ASCII string.  The class_name does not exist.  No space is available in class_name.  A member of type type is already in class_name.	 A

	      is_a(3) example

	      <?php

	      class WidgetFactory
	      {
		var $oink = 'moo';
	      }

	      // create a new object
	      $WF = new WidgetFactory();

	      if (is_a($WF, 'WidgetFactory')) {
		echo "yes, $WF is still a WidgetFactory
";
	      }
	      ?>

       Example #2

	      Using the instanceof operator in PHP 5
