difference between HTML, Java Script, CSS and PHP ?

Question

p0sitr0n · Answer

HTML is a markup language. So your HTML file does pretty much nothing except outputting some text, image, video in a fancy way
CSS is a style sheet language, which makes the HTML even more fancy
JavaScript is an actual programming language built in to the browsers. So you can actually compute stuff and make it do cool things.
PHP is the frontend to a server database. This is what you need to output, lets say , some user info from your database (usually SQL) to the user's screen so he actually sees a readable output . It also manages the access to the info (security purposes).

"PHP is the frontend to a server database."  I disagree on that.  While accessing a database can be important, it is just a server side scripting language.  The use of perl-cgi and other server side scripting languages were originally a bit cludgy.  PHP was written to address that issue for a Personal Home Page, which is what PHP meant.  It was able to be dynamic, which rapidly lead to database use, but it is not just a datanase frontend.
