Can I somehow chain methods in PHP

Question

Basically, I am looking for a way I could optimize the following. Not really a PHP programmer, and in the Ruby world this would be easy, but at the moment I have this:

if(count($methods) == 1) {
    $resp = $this->$methods[0];
}
else if(count($methods) > 1) {
    $resp = $this->$methods[0]->$methods[1];
}

Is there somehow a way I could loop over the methods array here, and chain them together?

Thanks!

"Methods" meaning a function you want to call, or a *property* you want to access? What you show is a property access, not a method invocation. — deceze, Aug 20 '18 at 11:19
If the method you're calling returns an instance of a class or property you're accessing contains an instance of a class, you can chain them. — M. Eriksson, Aug 20 '18 at 11:25
Do the methods actually need to be "chained", i.e. running against the *return value* of the previous one? Or do you just want to run an array of method names on a single object instance? — iainn, Aug 20 '18 at 11:35

What you want is essentially an array reduction:

$resp = array_reduce($methods, function ($o, $p) { return $o->$p; }, $this);

It's unclear whether you want $o->$p (property access) or $o->$p() (method call), but you can figure that out.

As I said above, yes they are properties, let me have a play with what you are showing here. – TheApeMachine Aug 20 '18 at 14:23
