People absolutely have VERY strong opinions and voice them constantly. True of every language but especially php. Almost feel like it’s more acceptable to rant about php than to praise it
I know I used to have the impression of PHP as a messy language because I last worked with PHP4. It's come a long way since then, though I don't use it.
I attended a talk by Rasmus Lerdorf at a FOSS conference in 2006. It has been a long time, so I remember only a few things from the talk, but one thing I remember him talking about is how people love to complain about PHP, often on forums that are themselves written in PHP.
