### symbol/character usage in code..?

Know this doesn't have too much to do with windows specific usage, but am working on/via windows installation of XAMPP myself, and am just wondering why in some new code am busy reviewing, they seem to be using sort of comment blocks inside code sort of like the following bit of text: ###start something # blah ###end of whatever Now, yes, in python, the # symbol is the comment character, but, can't imagine what this is doing in PHP, and, part of my reason for asking this question here is that google searches relating to the # character, or even searches in something like an offline .chm file are impossible, due to it's common usage in HTML, etc...<smile> Stay well Jacob
