What do these PHP statements mean?

folie=new mysql;new (instantiates) a MySQL class and assigns a value to the variable $folie

crazy=new myfunction;Similarly, instantiate the myfunction class and assign a value to the variable $crazy

folie->link("");Call the link() method in the instantiated $folie class and pass an empty string!

Hope it helps! Yes!

folie=new mysql;Create a MySQL object named $folie

crazy=new myfunction;Create a myfunction object with the name $crazy

folie->link("");Let $folie connect according to the default parameters.

I can only help you so much, because you're so little.

The first sentence $folie=new mysql instantiates the mysql class and assigns a value to the variable $folie

The second sentence $crazy=new myfunction is to instantiate the myfunction class and copy it to the variable $crazy

The third sentence $folie->link("");folie is a mysql class instantiated, so $folie->link("");is the link() method in the referenced mysql class.
