These topics always just smell of "Now I'm a grown up programmer I'm going to tell the world how much I understand by slamming an easy target language".

I love PHP and have used it for years since moving away from asp.net and agree with some of the posters arguments as a theoretical principle, but as day-to-day PHP developer I also say so what. Naming and parameter inconsistencies? Yes, my libraries have that too and I can at least learn the PHP ones with some experiernce. I don't know any asp.net developer that doesn't have to use some kind of tool to help them find where System.Obscure.FoundItOnline.Function exists in the monster .net namespace system. It allows me to be productive and allows me to be the gatekeeper of how well or poorly I implement things. This is a crucial point of the constant argument about poor PHP logic/presentation support for me, I can happily write mixed and messy code for a £500 job or I can write some clever system that implements caching and output buffer manipulation and have a great template system.

There are far too many people spending far too much time thinking that academic level programming considerations are applicable in every detail to every day programming practices of web developers.
