Synchronizing PHP method with dynamic names

I was wondering if it is possible to create a method chaining using the values ​​(or keys) of an array as dynamic method names.

For example, I have an array: $methods = ['first', 'second', 'third']

Can the next challenge be created?

first()->second()->third();

This has not been verified. Something like:

$object = null; // set this to an initial object to call the methods on

foreach ($methods as $value)
{
    $object = $object->$value();
}


Note that every method you call must return an object that has a method that will be called next. If it is an object of the same class, then it can simply return to itself using each chained method.

You can also use the eval function. Example:



$object = new SomeClass(); // first, second, third
$methods = ['first', 'second', 'third'];

$callStr = 'return $object->';

foreach($methods as $method){
    $callStr.= $method . '()->';
}

$callStr = substr($callStr, 0, -2);
$callStr.= ';'; // return $object->first()->second()->third();

$result = eval($callStr); // return result of call - $object->first()->second()->third();
