Is it intentional that the DOUBLE_COLON operator can be used on a
variable that contains a reference to an object?
<?php
class C
{
public function m()
{
print '*';
}
}
$c = new C;
$c::m();
Until yesterday I thought that only the OBJECT_OPERATOR (->) can be used
on a variable that contains an object. https://3v4l.org/59Xap proved me
wrong.
As the deprecation / strict standards notices suggest, though, $c::m()
does not invoke the method m() on the object referenced by $c. It
invokes the method statically on C (the class of the object referenced
by $c): https://3v4l.org/19taB
I think that using :: on a variable that contains an object should not
"fall back" to a static access on the object's class. Instead the
runtime should error out.
What do you think?
