Any good HTML, PHP, SQL editors/compilers available for pc?

Question

I just want to create, test and debug a web page.

Answer 1

Np++ is love, Np++ is life.

Answer 2

For creating code, use IDE (thousands of them: Atom, geany, Vi Improved...),
For testing and debugging HTML code use build-in browser's console.
For testing SQL (RDBMS MySQL), use MySQL WorkBench
For testing and debugging PHP, use inner try-catch, dump variables and so on (basically, use languages abilities to debug).
Also,
Those languages can't be compiled, but PHP can be pre-compiled.
Also also,
All of them can be interpreted by any browser, since they are web (excluding SQL, because technically, its not a programing language, it is a query language).

Answer 3

Notepad++ is basic and very limited imo. I would rather go for sublime text 3 with the appropriate plugins.
