Variable constant help.

[Chris92]

I was wondering if there is a way to get a constant by using a variable connected to it, eg:

 

define( 'CONSTANT_LOL', 'haha' );

$var = 'LOL';

echo CONSTANT_$var;

 

Any help is appreciated,

So I'll have to put them into objects?

No, that's only an example.

 

mixed constant ( string $name )

 

Just supply the parameter with the string value you want to get the constant value of -

 

echo constant("CONSTANT_$var");

Okay, thanks very much! Works like a charm.

Doesn't that deviate from the definition of constant? Change it's value by al means, create a switch/on/off gismo that's alright, but dynamically altering it's name, I would love to see the context of it application.

It seems like he has a series of constants defined and wants to dynamically choose which one to use based on an external variable.
