Yeah, I gathered that. Similar to when using 'use strict' in Perl, you have to define global, local variables etc.

also... global isn't really a function, it's a declaration that defines the variables scope.

sounds like it

Are these similar to 'use' and 'require' in Perl? In Perl, require is pulled in when needed, where an use block is evaluated at compile time?

Because require() inserts the contents of a file before processing, it comes in handy when you need to include stuff like common variables needed for a script in that page. Thats the most common use I have for it.

Otherwise, as theprofessional says, use include().

Global is an easy one.

Just use include() always unless you absolutely need to require() a file somewhere no matter what.

Is this the global you mean?

include vs require, the short version:
include()
include inserts the source code for a file when the include() call is read. If the file cannot be included, an error will be printed an error will be printed and the script will continue. If the include() statement is within IF statements, the file will only be included if the IF statement evaluates to true.

require()
require() inserts the source code for the file prior to processing. If the file cannot be inserted, the script will not continue. If the require() call is within IF statements, the file will be required regardless of wether the IF statment evaluates to TRUE or not.
