Dynamic constant name in PHP

Question

I am trying to create a constant name dynamically and then get at the value.

define( CONSTANT_1 , "Some value" ) ;  // try to use it dynamically ... $constant_number = 1 ; $constant_name = ("CONSTANT_" . $constant_number) ;  // try to assign the constant value to a variable... $constant_value = $constant_name; 

But I find that $constant value still contains the NAME of the constant, and not the VALUE.

I tried the second level of indirection as well $$constant_name But that would make it a variable not a constant.

Can somebody throw some light on this?

echo constant($constant_name);
