This blew my mind when I started to learn PHP.

The P in PHP stands for PHP.

Isn't it Personal Home Page?

Somehow in nearly a decade of working with PHP I did not know this. Got to love the recursion :)

@saDammie-Jr It was originally, then came the recursive backronym of doom.

Just like the G in GNU

Originally it was personal home page but then they renamed it to php hypertext processor. So actually it is personal home page hypertext processor. Phphp.

GNU's not UNIX
Wine's Not an Emulator
PIP Installs Packages

YAML ain't markup

Markdown ain't markup

Isn't it PHP Hypertext Preprocessor?

XAMPP Apache MariaDB PHP Perl

And H for HP

and B in Bee ._.)

XNA is not an acronym

Ah... Good Times...

The GNU Hurd kernel...

'It's time [to] explain the meaning of "Hurd". "Hurd" stands for "Hird of Unix-Replacing Daemons". And, then, "Hird" stands for "Hurd of Interfaces Representing Depth". We have here, to my knowledge, the first software to be named by a pair of mutually recursive acronyms.'

— Thomas (then Michael) Bushnell

@baskoros I thought the X stands for cross-platform (x-platform)
