By my knowledge I can only call the method of a class only if I instantiate or if the method is static!
I can just do something myself class->metodo('var') or class::metodo('var').
But I’ve seen in some codes something like class->metodo('var')->outrometodo('').
Drupal himself uses something similar. Ex:
db_select('node', 'n')->execute()->fetchCol();
How do you make that kind of call, and what would be the advantages?
@Virgilionovic even being in java the idea is the same?

Yes. It’s the same logic.
– novic
Yes, see working repl it.

Really! I read the question and the answer here, and it worked! Recommends that I delete the question?

You can’t leave... you’re like a duplicate.

But a question has not been answered! How is the question! What would be the advantages? Does it represent any significant gain? Is there any recommendation for when to use or not?
