       filter_array() returns an array holding the items of <arr>
       which passed sucessfully through the function <fun>  found
       in  object  <ob>.   The  function <fun> is called for each
       element in <arr> with that element as parameter.  The sec-
       ond  parameter  <extra> is sent in each call if given.  An
       object is considered to have  passed  sucessfully  through
       <fun> (and hence is included in the return array) if <fun>
       returns 1.  If <arr> is not  an  array,  then  0  will  be
       returned.
