What CAN’T I do with these 4 languages? Anything?

Ok, so I know HTML, CSS, and a lot of PHP. I just recently started learning Javascript/jQuery. I’ve heen hesitant to use it because I’ve seen it misused so much in web dev… which I mentioned in another post. Anyway, that’s the devs’ fault, not Javascript’s.

Anyway, in my basic understanding of the language, I can already see HUGE implications for webapps, namely UI elements.

My question is: What CAN’T you do with HTML, CSS, Javascript/jQuery and PHP/MySQL? It would appear that if you know these four (really five languages and one library), there’s nothing on the web you CAN’T build.

I don’t think you can. Actually, you can pull some tricks with HTML (especially with `

To get back to your initial question, I think you won’t be able to do complex application. For example, CodePen is built upon Ruby if no mistake.
Actually, you will be able to do that, but that doesn’t mean it’s the best choice.

which is why there are things like [APC](http://devzone.zend.com/1812/using-apc-with-php/).

not really… did it blind my first time. (probably not recommended.)

Check out [this](http://board.phpbuilder.com/showthread.php?10390043-Ever-Been-Ha-gt-lt-0r3d), though (good info starting at post #7). I’m going to be adding [samhain](http://la-samhna.de/samhain/s_documentation.html) to my clients’ servers as I have the time.

I _would_ recommend being comfortable with the command line (you don’t have to know it all; just the basics + installs and how to research commands) and knowing how to set up SSH.
