Hi,

I know that it is possible to build up a variable name based on a
string and another variable name i.e.

$varnum=5;
${"varnumber_$varnum"} = 'This variable should be called varnumber_5';

but is it possible to do this for a constant? For example I may have
constants set up as

define('CONSTNUMBER_1', 'This is constantnumber 1');
define('CONSTNUMBER_2', 'This is constantnumber 2');
define('CONSTNUMBER_3', 'This is constantnumber 3');

and I may want to access them from inside a loop i.e.

for($counter=1; $counter<=3; $counter}}) {
echo 'Contents of current constant = ' . ${"CONSTNUMBER_$counter"} ;
}

Now obviously this doesn't work because it sees
${"CONSTNUMBER_$counter"} as a variable but if I try and take the $
off then I just get errors.

Can anyone help? Does this even make sense? :-)
