Question

I’m having an issue with the following code. I’m just guessing it’s a scope problem.

public function run() {

    return eval('$this->config();');
    // This will return null.

    return $this->config();
    // This will return my config array right.

}

Before anyone asks:

1. Not both return are ‘active’ when testing.
2. I know eval is evil, but i’m building some kind of terminal for admins to run PHP code.

Do anyone have any suggestions about this terminal thing? (My basic problem is still with the eval…)

Answer 1

eval is returning NULL because that is what it is suppose to do. Right from the documentation page:

eval() returns NULL unless return is called in the evaluated code, in which case the value passed to return is returned.
