it is because of the statement "global $movie_name" inside the function that the function can access the variable.

So which one is best to use, arguments or global?

Thanks for clearing it up for me anyway guys!

:)

Usually it's a good idea to use function arguments instead of global(izing?) a variable. Using arguments helps separate the function from the rest of the script, allowing it to be much more "modular" and increase the chance of code reuse. Using global variables ties the function to that specific script, so you probably can't take that function and use it on another project without modification.
