Hello everyone,
I have a question about the internals of PHP, but this is not about
advancing the development of the language, so I apologize if this is
on the wrong list. I am choosing to post to this list because I
believe the people here are most qualified to answer my question.
This is what I want to know: Is there any valid situation in PHP where
the ‘parent’ keyword is not followed by the scope-resolution operator?
I am asking to help me decide on the best way to fix a bug for
php-mode[1] for GNU Emacs. Consider these three lines:
echo $parent;
echo parent::$foo;
echo $this->parent;
Emacs correctly highlights the first ‘parent’ as a variable name. It
also highlights ‘parent’ in the second line as a keyword, as it
should. But in the third line it treats ‘parent’ as a keyword instead
of a variable and applies the wrong syntax formatting.
My idea to fix this problem is to only treat ‘parent’ as a keyword if
the scope-resolution operator immediately follows it. But before
doing that I want to know whether or not that is true. So is there
are valid situation where the keyword ‘parent’ does not have ‘::’
after it?
Thank you in advanced for any advice and help.
