The reason your script does not doing anything is because you never call one of those inner functions, all you ever do is define them.

 

That said, PHP doesn't really support nested functions.  The script will parse successfully, but if you ever call the outer function (big_func in your case) more than once you'll get a Fatal error about re-defining the functions.  There really isn't any pratical use for trying to do a nested function setup, just declare all the functions at the top global level and then use them as needed elsewhere.
