Use variables in functions


Recommended Posts

I have a website in which a function is called hundreds of times. There is a variable in the main program that I need within the function, but it's not there. I could add another argument containing that variable

instead of

but then the program would become a lot bigger! So is there a method that doesn't require so much extra data?

An easy patch is to use the global keyword, but usually this kind of situation indicates a fundamental problem with your software's design and it might be worth redesigning your software to make future maintenance easier.
