     a reference to an external resource. Resources
     are created and used by special functions.

>&#13;     Due to the reference-counting system introduced
     with PHP4's Zend-engine, it is automatically detected
     when a resource is no longer referred to (just
     like Java). When this is
     the case, all resources that were in use for this 
     resource are made free by the garbage collector.
     For this reason, it is rarely ever necessary to
     free the memory manually by using some free_result
     function.
