I'm just starting to learn php and have a quick question. I'm making a
site with file includes. so for example my default page will be:
index.php and services page with be called services.php
BUT... I want to link to services via this method: index.php?vw=services
Still no problem there.
BUT on the index.php I want to write this if statement:
if ($vw == "") {
write this code
}
But then I get an error that the var is non defined. Do all vars in PHP
have to be defined first? If it isn't defined, doesn't the program
assume it's value is nothing?
