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;


[...]

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?


Hello Eric

Wouldn't it be simpler to check that parent if preceded by
whitespace/brackets?  Checking if it's followed by the paamayim
nekudotayim, seems also ok.


Thanks for the idea.  Checking for brackets would work but not
whitespace since PHP allows programmers to write code such as


    echo $this->  parent;        // Same as $this->parent


So perhaps checking for paamayim nekudotayim would be best.
