Look this example. This is not PHP but let say that is what I am looking for:

Look in the right bottom corner of each post. There is button "cituoti+". It means "quote+".
So you just go all page down and mark what you need to quote. Than you just press "atsakyti" button which means "post reply". I know it is similar to PHP3 QUOTE and tha QUOTE each post but PHP3 way is much more complicated. And also you cant UNQUOTE like in my example. When you press cituoti+ you get cituoti- so you can quote and unquote as many times as you want and with no effort.
I hope you understand what I mean....
