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

That is strange. Try to see if variable is part of defined variables:

$vars = get_defined_vars();
print_r($vars);

Also, If your variable exists in a function, you can globalize it with global keyword.
