Call PHP Class method using variable instead of actual function name

Question

I am having a problem with accessing Class methods using variable instead of function name. Like in below example:

class Test
{
    public static function route()
    {
        $functionName = "myFunction";
        echo self::$functionName;

    }

    public static function myFunction()
    {
        return "Hello";
    }
}

I am getting error message:

Fatal error: Access to undeclared static property: Test::$functionName

Is there a way of accessing class methods using variables containing function name? Please help :)

self::$functionName()

Calling a function usually done with (). So you have to add () to your echo self::$functionName; so it will become:

public static function route()
{
    $functionName = "myFunction";
    echo self::$functionName();
}
