    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. -- ejmr 南無妙法蓮華經
