I have a function in a class with this code:
$this -> userDb;
$error = $this -> error;
print_r($error);
userDb is another function in this class and error is generated by userDb. It always gives a non-empty array.
Why wouldn't I be able to get the value of $this -> error?
First userDb is function but you aren't calling the function. You have to call userDb as
$this->userDb();
to call a method (function) you must use parentheses:
$this->userDb();
Without seeing the code for the userDb function, it's difficult to explain why the error is caused. However, if you're trying to call the function, you need to include the brackets in the function call:
$this->userDb();
print_r($this->error);
