You're right, but just a slight clarification: Well, PHP isn't an HTML parser and has no concept of a DOM, or the SGML-based nature of HTML, or anything like that (although there are extensions which do this). Essentially, PHP generates a series of bytes, which are output. In a web environment, this obviously means 'sent to the browser', and typically implies HTML output. But you can also output WML, csv, LDIF, or any other text-based format; or, for that matter, binary data such as JPEG, GIF, PNG, or whatever. This means that PHP is *required* to output whatever it is asked to--regardless of whether it might look like HTML or not.
