Question

How to document PHP constants:

define('SOME_CONSTANT', 'constant value');

with Doxygen?

Answer 1

Just include a documentation block above the constant define() function call or const keyword like this:

<?php

/**
 * Short Break Adventure Trip Sub Type Id
 */ 
const TRIP_SBA = 1;

/** 
 * Small Group Adventure Trip Sub Type Id
 */ 
define('TRIP_SGA', 2);

?>
