[SOLVED] Unset(); and mysql_close();

[MemphiS]

Just wondering with unset(); Any real point for using unset(); unless for closing sessions. eg: unset($var); Will this take a load off the server? make speed better? jut wondering

 

With mysql_close(); Should i always use this to close the connection?

 

Thanks for your responces

unset() will free memory associated with a variable.  It's only useful if you want to re-use that memory in the same request.  The memory will be freed when the script finishes anyway.

 

As for mysql_close(), again it's closed at the end of the request.  You only need to close it if you have a reason to close it before the request is finished.
