How else can you substitute a method call?

Question

Zend Framework

$res = $this->$method['name']($parser_name);
Question 1 I came across this code, is it normal from the point of view of OOP?
serginhold fully answered this question. I knew that the code for substituting the method, but I thought why do it, it turns out you don’t need to do it

$method = 'getName';
$obj->$method(); // $obj->getName();

$method = 'getTitle';
$obj->$method(); // $obj->getTitle();

Question 2 Is there a better way to do the same?
I think it's better to rewrite the program logic so that such things do not need to be used at all, but I wonder if you still need to use such a "method auto-substitution" correctly?
The answer of hack504 seems to me the most correct from the point of view of OOP, I'll go and read about reflection

$this->{$method['name']}($parser_name);
//можно и через рефлексию: 
$reflectionMethod = new ReflectionMethod($this, $method['name']);
$reflectionMethod->invoke($this, $parser_name);

Answer 1

nothing, usually it looks like shit code, because situations where this is needed are extremely rare
sense in passing the name of a method or property through a variable, and that's it. Type in one case such a method, in another another

$method = 'getName';
$obj->$method(); // $obj->getName();

$method = 'getTitle';
$obj->$method(); // $obj->getTitle();

ps the question is being edited on the go .. if the author asked "what is the point of doing this"
