Re: use of mysql_free_result and unset

It's done at the end of a function, or at any other time, when the variable is no longer in scope. You really only need this on a large, long-running script or where memory is an issue... For web-sites, that's quite rare. For a shell script, it might make sense. -- WARNING richard@zend.com address is an endangered species -- Use ceo@l-i-e.com Wanna help me out? Like Music?
