PHP ->

[icydash]

Hey guys, what does the -> do that i see so often used in code? I've been programming PHP for years and never had to use that, and was finally just wondering what it did.

Thanks!

Example of what i mean:

$this->set_title($this->lang->login_header);
$this->tree($this->lang->login_header);

It's an operator for object-oriented PHP code indicating that the item on the right is a member of the object on the left.

oh so it defines whatever is on the right as a member of what's on the left? cool, good to know. thanks!

No, it doesn't define it, it accesses it; the relationship is already defined elsewhere in the class definition.
