The numbers tell a different story. Wordpress powers 25% of the entire web. That is a quarter of the entire internet. It's pretty much your opinion vs the entire internet.
You can see how your opinions come off as ludicrous ?

The customers are telling you PHP is preferred to other languages and is here to stay as evidenced by 25% of the web using a single PHP application as the backend.
This is a straw man. Citing 2 popular web sites and 1 application doesn't mean PHP is a well designed language. You could just as well have picked 2 other web sites written in Java to argue that PHP is rubbish.
I wouldn't even call it influential, unless language developers have been inspired about how not to design a language. Popular, yes, but not influential. I don't see anything from it being incorporated into other languages. It generally seems to have been playing catch up in terms of features, in a similar way to javascript (where there it's less about catch-up and more about breaking out of the browser & supporting OO).
