Actually, it has nothing to do with lexical scoping. It's more subtle
than that.

I believe that if you try to make a second connection to MySQL via PHP
that's identical to an existing connection, then PHP will reuse the
first connection. That's why mysql_connect() returns the same resource
handle.
