syntax of $this-> object -> object ?

[byte1bit]

Hi there. There is one oop syntatictic form that i can't really understand:

PHP Code:

 $this-> object -> object 


i have seen it in some php oop scripts. particularly in Alejandro Gervasio's http://www.devshed.com/showblog/1378...o-Composition/. Could someone clarify the syntax, and the name of this form? I have submited this question there, but it doesn't show up anywhere

thanks for any answer
