Hi. I can't seem to find the page in the online manual about this thing -> (operator?) -- can anyone point me in the right direction? Thank you very much.

Thanks. That I already knew. My questions are very specifically just what's in the thread title:

What is it called?
Where is the page about it in the online manual?

Thank you.

Hello. No thank you. You are trying to help but you are not answering the questions, only making it more confusing. Please stop posting unless you have the answer -- but thanks for the help, it is deeply appreciated.

Again I simply have two specific questions (with specific answers):

What is the this thing -> called? (specifically)
Where is it explained in the PHP manual?

Thanks very much for any assistance. Cheers. 🙂

I do not think PHP has an official name for it, but "member of" operator might be appropriate (the right hand side is a member of the left hand side, which is an object, or sometimes, a class).

In both the sections on PHP4 OOP and PHP5 OOP in the PHP manual.

Thanks.

I can't find any mention of "member of" in the PHP docs.

Does anyone have a direct link (I don't have enough time to read the entire section on OOP) which explains this operator in detail? Thanks very much.

Because I gave it the most descriptive name I could think of. As I noted, there is no official name for it, as far as I know (possibly not even in C, from which it is indirectly derived... though in C++ we would simply call it operator-> heh).

There is nothing much to it. Given an object $x and its member variable m, $x->m allows you access the member variable m of the object $x. If m is a member function instead, then the syntax changes to $x->m(arg), where arg is some argument passed to the member function (or $x->m() if no argument is passed, etc).

Thank you very much for taking the time to help. Cheers.
