Is there any way that this can be done? 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 -- CC
