what does mean array($this, $some_method_string )?

Question

Sorry if it might appear very simple, but what does that mean:

array($this, $some_method_string)

in this piece of code:

array_map(array($this, $some_method_string), $some_data)

Answer 1

array($this, $some_method_string)

it is a valid callback , calling the method $some_method_string on $this :

with array_map , for every element of $some_data , call $this->$some_method_string(currentElement)
