PHP variable defined in 'parent' file not recognized in 'required' file

Question

I am trying to access a variable defined in parent file from inside the required file, like this:

<<< parent.php >>>

$controller = \'index\         


        

Answer 1

Alright, Got the issue here. It was a mistake of mine, I guess. The error was not in the above lines, but somehow another variable was rather than accessing the parent php, was accessing the child php directly.

So, guess, it works out now, why the variables were not available.
