"I'm not a real programmer. I throw together things until it works then I move on. The real programmers will say "Yeah it works but you're leaking memory everywhere. Perhaps we should fix that." I’ll just restart Apache every 10 requests."
I mean, I'd be first person to tell you that I am a scripter at heart, but I would never, ever say "I don't care about this [computer science] crap at all." I feel like my job is to defer to the many programmers that are smarter than I am. Including the parser and compiler and linker etc
These quotes aren't terrifying they help explain why something such as PHP is so successful. The general philosophy was, and still is building something that spits html and can connect to a database in a few lines of spaghetti code. Granted there is a movement in PHP that is as religious regarding TDD,OOP as in the Java world, they don't represent the majority of PHP devs.
PHP execution model satisfies 2 crowds : hosting service providers that can provide cheap hosting to the second group of people, hobbyists that just want to install wordpress or write a "dynamic" page.
The later will never care about OOP,TDD,FP,Agile, and stuff like that. In PHP you begin with writing HTML then you put the PHP code. not the other way around,no matter how hard "advanced users" try to deny that fact, PHP scripts begin with a TAG,it is,first and foremost, a templating language that generates HTML files.
The sad thing is that it could have been done a better way. But serious language designers were too pedantic and arrogant to write simple solutions. Rasmus lazyness paid off ...

And untold tens of thousands of companies using PHP to drive their corporate internet presence.
"We have things like protected properties. We have abstract methods. We have all this stuff that your computer science teacher told you you should be using. I don't care about this crap at all."
I kinda agree with that sentiment. There's a lot of unnecessary stuff going on in CS. We had extreme OOP and I fear extreme FP will spread into the mainstream. The mission of programming language designers should be to help programmers do their jobs better, not design something elegant/interesting/powerful/expressive/[buzzword]. Those things are all good, but only in the service of programs with fewer bugs and shorter time-to-market.

That may be true for programming language designers, but I'm afraid you misunderstand what CS is all about. Hint: it's not about time-to-market. The job of CS is to explore the theory -- precisely how to do something in interesting/elegant/expressive ways. Its job is to explore the theoretical and practical underpinnings of computing; to provide proofs; to explore the abstract and formal systems behind software. CS is not necessarily directly applicable to enterprise software (though of course CS research does have practical applications; and of course there is overlap between theoretical and practical computing).
A lot of cognitive dissonance comes from people who look at CS thinking it's what they need in order to write software.
This is ridiculous. I think you are seriously missing the point of PL research. Furthermore, I can not even imagine what your definition of "helpful" is when you say not ".../powerful/expressive/...". I honestly can't even argue with you if you do not think power or expressivity is beneficial.
PL is not a buzzword-oriented culture. No (serious?) language designer creates a language with the intent of making it harder for programmers to do their jobs. (Brainfuck and other Turing traps excluded.) That said, being "helpful" can be interpreted in many different ways. And of course, every PL designer does interpret it differently!
OOP took off because it was a revolutionary way of structuring your code so it could be easily used, reused, and maintained. The point was to help teams be more efficient!
Functional Programming is so worthwhile first off due to immutable types. This allows highly parallelizable code. You don't have to worry about race conditions because your objects are read-only! The emphasis on types also allows better ability to prove correctness of a program before run-time. Finally, all FP languages (that I can think of) are highly expressive. This means that you can write the same program in (OCaml, Haskell, CL, Clojure) in a shorter amount of time than you could in Java/C#/Obj-C.
If you still think there is "a lot of unnecessary stuff going on in CS", I'd really like to hear what you think is necessary and we'll go from there. I already discussed your "fewer bugs and shorter time-to-market" points.

I'm not sure where you're going with that. I have stared at enough medium- to large-sized codebases to realize that an excellent way to "fewer bugs" is to protect programmers against themselves and restrict their proven ability to shoot themselves in the foot (especially in the absence of code review and/or competent technical leads). Shorter time-to-market is actually a different property. PHP or Rails got popular because they make it easy to crank out a web application in a relatively small amount of code. However, this often doesn't translate into "fewer bugs" when the codebase gets big.
I don't know what "extreme FP" mean, but there is a night and day difference working with referential transparency and immutable data structures in terms of cognitive load and ability to change parts of the system with confidence (for the record, I'm also mystified about "extreme OOP").
PHP is (admittedly slowly) moving in a positive direction because of community effort, Rasmus' opinion shouldn't terrify anyone since he's just one vote of many.
I'm of the mindset from 1995-2005, computer science and software engineering didn't exist while the web matured. PHP was major player in this time, as was Perl. Perl could have "won" just the same as ColdFusion, or VBScript.
It took a decade for these web programming communities to introduce and/or build on ideas from 1958. Long before the web.
PHP is better, however Rasmus' philosophy (while ok at the time) permeates PHP's design and it hurts. It hurts a lot.
> Perl could have "won" just the same as ColdFusion, or VBScript.
Perl was far more widespread early on (96-99) than PHP was, but it was quite painful to deal with compared to PHP. PHP made web stuff dead simple, and that's why it 'won'. CF and VBS never really stood a chance because of the extra costs involved. iHTML, HTML/OS and others were all vying for a foot in the door at this stage, but all were second-run players charging money for something that 99% of hosts were never going to pay for, and therefore devs wouldn't get exposed to those tools.
The funny thing is, despite being originally inferior in everything but simplicity compared to Perl, PHP has added feature upon feature (usually poorly thought-tout) over the years, and nowadays looks like a poorly-designed Perl with a terrible standard library.
And an absolutely enormous installed base as well as a huge amount of code available for use. It's funny how it succeeded so well in spite of being a fairly crappy language.
It really illustrates how useful a quick way to get started with the language is. PHP could provide something useful to the author and others (web content) almost immediately, while Perl required you to understand CGI (to some degree) first. In some respects, PHP's lack of features was beneficial, as each missing feature was something people didn't have to learn about, even if tangentially. No packages or namespaces? A poor module ecosystem develops, but devs didn't need to think about how it worked for the most part.
I suppose the thing is that Perl is a general-purpose programming language that was not really optimized for the Web whereas PHP started out with no ambitions other than being a Web templating language, which made it easier to get started with.
