Re: Dynamic constant names -SOLVED

My apologies for assuming too much of the variable names. Thank you for correcting me. Your response has caused me good confusion though. If I remove the ${...} notation I get quite a different output (specifically, there's no output). Are you sure the parser ignores it? This is the code I suggested WITHOUT the ${...} that returns nothing. $test_name="ta_dah"; define("constant_name","test_name"); $constant_value=$constant_name; echo $constant_value; And I wonder too if my odd usage of ${...} notation is improper in variables. When I want to create a dynamically named variable (as opposed to my off-topic constant example), I use: ${$variable_name}="value"; or even ${"fixed_string".$variable_name}="value"; I hope I'm not going against sane practices in doing so.
