Question

I can’t figure out why I get this error:

Parse error: syntax error, unexpected ‘.’, expecting ‘,’ or ‘ in Settings.php on line 5

Here is the code

class Settings
{
    public $appDir = 'app';
    public  $controllersDir = $appDir . '/controllers';

}

Answer 1

You can not execute arbitrary code in the class definition. You can only declare values (static strings, numbers and arrays with static information).

If you want to dynamically add values, you would have to do so in the constructor.

class Settings 
{
    public $appDir = 'app';
    public $controllerDir = '/controllers';

    public function __construct()
    {
        $this->controllerDir = $this->appDir . $this->controllerDir;    
    }    
}
