Why is my constructor still called even if the class and constructor case are different?

Question

I am surprised for why the constructor is called when we have different class and constructor name. Constructor name is starting with small \"r\"?

class Regi

php is case-insensitive (sometimes). The following would work as well:

CLASS REGISTRATION {

    FUNCTION reGISTration(){
        ECHO "constructor is called.";
    }
}

$obj = NEW Registration();
