The title pretty much explains it all! I have a variable which holds the site's root url, but to make it work online and offline on my xampp, I need to make some differences. When the end variable is output, there are two "intermsediary" ones I used to hold stuff, like the position of a slash in a string.
Once I have the end variable is it advisable to unset() the ones I don't use any more? Does this just use up more resources than it gains?
I will be looking around the web for php efficiency and resource usage, but if you could point me to your favorite articles/locations I'd be really thankful.
Thanks a lot!
