It should be no surprise that structured and organized PHP is better than raw PHP, and that examples of well written PHP would probably involve a framework.

Although I suppose it could be argued that since PHP is intended for the web, it shouldn't need a framework, and it should support more of the features a framework provides out of the box than it does. Nevertheless, the pattern of a framework is as useful in PHP for the same reasons as it is elsewhere, so I don't believe it says anything negative about the language per se.
