Your error_reporting level must not be all the way up to E_ALL, because
when I tried your code PHP reported errors that might have helped you solve
the problem. Try this:
// We set up the constant
define("CONSTANT_1", "Some value" ) ; //constant name must be in quotes
// Later we try to use it dynamically ...
$constant_number = 1 ;
eval( "echo CONSTANT_$constant_number;" ) ;//tell PHP to treat the name as
code not as a text string
