Use variables in functions

[Francis_and_Hobbel]

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

function_name($a,$b,$required_variable);
instead of
function_name($a,$b);

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.

I tried global and ik works. Thanks!
