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.
