Re: Remove vars from memory?

The point of using a high level language like PHP is you can just ignore it. Let's say you decided to: if ($temp) { /* something */ } unset $temp; // save a couple bytes of memory And you decided to reuse $temp a few weeks later: if ($temp) // never will execute because you forgot you unset($temp); { /* something */ } So unless you're dealing with an extreme scenario (i.e. a number of very large mySQL queries), you probably don't need to worry. -Dan
