new Object()->function() ?

[Mtr]

this results in "unexpected T_OBJECT_OPERATOR" Parse error

How do I do this, without needing two lines such as

$o = new Object();
$o->function();

Also, what does "unexpected T_OBJECT_OPERATOR" mean?

(new Object())->function()

It means that the -is unexpected at that point.

You don't. That syntax (new Object()->function()) isn't supported.
That's why you get "unexpected T_OBJECT_OPERATOR."

Yes, thanks, but more precisely: the "->" is not an operator, nor is it
text. (I assume that "T" is short for text.) So it's unclear what this
error msg means.

Let me refine my example, so as not to use any reserved word like
"function"

$o = new MyObject()->myFunction() does not work:

If I know what the error means, it will be easier to remember.

The T is short for "token."

It is an operator, like "::".

The "T" means token.

The parser simply doesn't expect a "->" token at that point.

$o = new MyObject()->myFunction() does not work:

The message is pretty clear. PHP doesn't support this syntax.

oh really? then perhaps you can tell us what "operation" is being performed

The object is dereferenced. From the manual:

| An operator is something that you feed with one or more values (or
| expressions, in programming jargon) which yields another value (so
| that the construction itself becomes an expression).

quoting the manual can only try to indicate what the authors of PHP say.
That is not any proof that it really is an operator. If they say that the
sun is blue, would you believe that, too?

The fact is that no operation is being performed, and so "->" is not an
operator in the conventioned use of the term.

In another language, Object.property would not indicate that the dot is an
operator of any kind. The author(s) of PHP shot themselves in the foot
early on when they decided to use the the dot for string concatenation
rather than the same plus sign that nearly everybody else uses. So now they
have to use the clunky '->' where they should be using a dot. It still just
denotes that a method or variable belongs to the object.

for instance, from the manual on Classes and Objects:

"To create an instance of a class, a new object must be created and
assigned to a variable."

That is just not true. The fact that it is in the manual doesn't make it
more true.

But there IS an operation being performed. You are dereferencing the
object. And it has precedence (pretty high) and associativity (left to
right).

In another language, Object.property would not indicate that the dot is an
operator of any kind. The author(s) of PHP shot themselves in the foot

rather than the same plus sign that nearly everybody else uses. So now they

denotes that a method or variable belongs to the object.

And in another language (specifically C++ or Java), the dot is an
operator.

lol. i was going to ask him what term he gave a 'dot'...seems like 'denotes
that a method or variable belongs to the object' is a bit looong AND obtuse.
