I get that the name PHP is a recursive acronym. Fine

I'm not sure why PHP has parts of the preprocessor and Hypertext in its name.

A preprocessor is a program that processes input data, and its output is the input of another program.

PHP seems to me like a translator. What exactly does a preprocessor do?

Is it called a preprocessor because its output is usually sent to a web server for delivery over the Internet? So is this a preprocessor for the web server? Is this where it gets its preprocessor name?

Does it get part of the hypertext of its name because PHP is embedded in HTML?

I just found out why PHP is called PHP Hypertext Preprocessor, or is there something else, or am I mistaken, and is it something else?

I have never read what makes PHP a preprocessor and why it has hypertext and a preprocessor. I would really like to nail this.

The hardest part of the entire PHP programming language is its name.
