pdoc is (or rather, is planned to be) a PHP documentation generator and viewer.
Currently, pdoc is a basic replacement for pman, the offline CLI documentation viewer provided by the PHP project. pman is a small wrapper script for builtin man command along with the function and class documentation from the PHP website in manpage format. It also appears to have not been updated since the PHP 5.6 days.
The easiest way to install pdoc is with Composer:
composer global require pdoc/pdoc
Then make sure $COMPOSER_BIN_DIR is in your $PATH.
Usage is easy:
pdoc <class/function name>
For example:
pdoc DateTime
More features are planned, so stay tuned.
Yes, really.
Does the world need this? Probably not. There are a number of mature, feature-rich documentation generators available for PHP, and you're certainly better off using one of them (at least for now!). In no particular order, here's a few you might want to look at:
So why do this?
The TL;DR version: because I can.
The slightly longer version: I've used all of the listed documentation viewers on various projects over time, and none of them really worked particularly great in my opinion. So I took a peek under the hood to see how they worked, and started wondering if I could do any better. Eventually I got to the point where I decided to give it a try.
