php define and after use unset vars (not working)
<p>I'm having memory problems with my server (server down right now) so I need to find a way of free memory after use.</p>

<p>My app uses mysql records witch i use as defined variables.</p>

<p>I was guessing I could fill in a array, use values when needed and at the end unset all, but my test doesn't work...</p>

<p>here is my example code, hope you can help, thanks</p>
