PHP

It stands for PHP Hypertext Preprocessor? The definition of itself is a stack overflow?

Also, (1+1) . 2 = "22"?

Please, somebody....

Recursive acronyms are a thing
Eg.
GNU: GNU's Not UNIX
WINE: WINE Is Not an Emulator

I don't think you know what a stack overflow is

nice grafic interchange format!

Y'all are forgetting the best recursive acronym.
LAME - LAME Ain't an MP3 Encoder

What is wrong with (1+1) . 2 = "22"?
You are concatenating, did you expect something else?

You do string concat and wonder why it's a string?

It thought it started as Personal Home Page

Yup. It probably would be named Hypertext Processor, but HP was already taken and recursive acronyms are a cool, I guess.

Also, "dot" in PHP is the concatenation operator, so you are summing 1 to 1 and concatenating a 2 to the result, giving you a "22" string. PHP is weakly typed, you know.

Guys, Personal Home Page. How'd guys forget it!
