$_GET is a superglobal, which just means that it is always available
everywhere. If you assign $custname to $_GET['custname'], you now have a
regular global variable (if the assignment is done outside a function) or a
local variable (if the assignment is done within a function).
So, either just use $_GET['custname'] everywhere you need it, or work with the
variable scope like you would have to if it was anything else. For example:
1. $foo = $_GET['foo'];
2. $foo = 'bar';
The variable scope of $foo would be the same, regardless of which of those
assignments were made.
Hope that helps.
