What I have discovered is re-using the $req variable is fine. While re-

works fine and sometimes it doesn't. When I use different variables like
$res1 and $res2 the mysql queries always succeed. Is the initial
approach of re-using variable wrong if variables contain a
resource(reference type)?

In other words since PHP uses garbage collection re-using the same
variable can cause problems. Is this true?

Google: mysql free result

Thanx, but that doesn't address my question. I may have another type
of resource other than mysql result. So, should I be concerned about
re-using reference variables in PHP bound to some resource?
