PHP Question

Get value of dynamically chosen class constant in PHP

I would like to be able to do something like this:

class ThingIDs
const Something = 1;
const AnotherThing = 2;

$thing = 'Something';
$id = ThingIDs::$thing;

This doesn't work. Is there a straightforward way of doing something equivalent? Note that I'm stuck with the class; it's in a library I can't rewrite. I'm writing code that takes arguments on the command line, and I would really like it to take symbolic names instead of id numbers.

Answer Source

$id = constant("ThingIDs::$thing");
