what is passed with the $this parameter ?

Hello Guys,

I came across the following code today while doing a code review.
The new instance pass the $this parameter, but I don't never see this variable in the class.

What does $this parameter pass to the Select instance ?

Code: Select all

 public function select(array $columns = ['*']): Statement\Select
    {
        return new Statement\Select($this, $columns);
    }

If this code is within a class, "$this" refers to the current instance of the class. You can read a bit more about it here
