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. -- ejmr 南無妙法蓮華經 -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] Double-Colon Always Follows the 'parent' Keyword?
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.
