Ewww, You Use PHP? (2010)

Because PHP really is so trivial to cut and paste, and will often "just work" (as in, be interpreted w/o syntax errors and produce some output), the vast majority of PHP code actually out there in the wild is absolutely terrible and leads to an insane number of vulnerabilities on the Internet, not to mention complacent developers who do not really understand how/why their code is working.
Obviously it's POSSIBLE to write excellent, performant, secure PHP code - see Facebook and, presumably, Mailchimp - it's just that virtually everything in the PHP ecosystem is fighting against you.
While I suppose Laravel and co are trying to reverse this trend, they just aren't what the "average PHP developer" is actually using - the median PHP developer is almost certainly copy pasting snippets from Stack Overflow into their hobbled-together Wordpress theme.
Mind you, this position isn't due to any logical or rational reason. I've recently had the opportunity to take a deep dive into Laravel after a long hiatus from PHP. It's come a long way. I simply find the preponderance of '$' characters in the code to be visually and aesthetically unpleasant. Every time I look at PHP code, I literally feel like my eyes are being assaulted.
The rest of the interface still looks like PHP - there are PHPSESSDATA cookies used throughout.
Note their 2014 update:
And yes, we still use PHP.
