PHP: echoing a constant with a variable name

Question

How can I do that?

I have something like:

define($stuff.'_FOO', 'whatever');
echo $stuff.'_FOO';

and it doesn't work :(

I just want to echo the constant's value...

Answer 1

First make a constant:

define("FOO_BAR", "something more");

then you can get the value by using constant():

echo constant("FOO_BAR");

Read more about constants in the manual.

Answer 2

Check out constant().

In your case:

echo constant($stuff . '_FOO');
