Operator for functions in PHP

+1 vote

What is the "->" operator for functions called?

At the bottom of PHP: Operators - Manual ( is the note:

"The -> operator, not listed above, is called "object operator" (T_OBJECT_OPERATOR)."

It has been down-voted 81 times. Is that because the operator is not called the "object operator"? Or is it because the note says that the operator is not listed?

I apologize if my criticism is not appropriate, but the operator is not properly documented. The "->" operator should be listed among the other PHP operators and there should be documentation of it.

The C++ standard calls the "." and "->" operators the "dot" and "arrow" operators, correspondingly. For example, see "5.2.4 Pseudo destructor call" in:
That is the latest draft of the newest C++ standard.

PHP can call its "->" operator whatever the designers decide, but there should be a definition to eliminate the confusion of different names depending on personal preference. A book I am reading calls the operator the "arrow operator". Is it called the object operator (as implied by the tag) or the arrow operator or something else?

There is a difference between a token and an operator, I think people usually confuse the two. The -> is a parser token, indeed called the T_OBJECT_OPERATOR (not sure why that comment was downvoted).

Here is a complete list of PHP's parser tokens:

I am working on an OOP project, and cannot decide which way to follow when I have to write a simple function.

For example, I want to write a function which generates a random string. In an OOP environtment, it is a matter of course to create a static class and a static method for that. But why? Isn't it more elegant, if I implement such a simple thing as a plain function? Not to mention that a function is more efficient than a class method.

So, in object-oriented programming, what is the best practice to implement such a simple function?
