Call a PHP function dynamically

Question

Is there a way to call a function through variables?

For instance, I want to call the function Login(). Can I do this:

$varFunction = \"Login\"; //to         


        

Answer 1

I successfully call the function as follows:

$methodName = 'Login';
$classInstance = new ClassName();
$classInstance->$methodName($arg1, $arg2, $arg3);

It works with PHP 5.3.0+

I'm also working in Laravel.
