PHP - Fatal error: Unsupported operand types

Question

I keep getting the following error and I was wondering on how to fix?

Fatal error: Unsupported operand types in C:\\wamp\\www\\tuto\\core\\Controller.php on          


        

Answer 1

The solution is in the error. You are trying to sum two value that has different types. You are summing array with normal value;

$this->vars +=  $key;

$key shouldnt be an array

Or second option;

$this->vars should be an array
