Perfect! I tried but I couldn't find anything that useful on Google.

You're right, but it's gone 3:30 in the morning and I didn't have the
energy to go searching for other groups

Besides, I like the people here.

this may give you an idea for doing this.
(btw. i dont think you are allowed to have variable names that start with a
numeric)

<?php
$a1a = 'Something';
$a1b = 'Something else';
$a1c = 'Something else entirely';

$code = 'b';

$vvv = "a1" . $code;

echo $vvv . '<br>' . $$vvv;

Yes, 'tis the easy way.

I think you could also get the same effect using syntax similar to Dan's
(for the sake of argument + alternative ways of doing things + to show off):

$1a = "Something";
$1b = "Something else";
$1c = "Something else entirely";

// Run /danielsscript?code=b

print (" Blah blah blah: ${"1" . $code} "); // Variables somehow merge
as one

// Result: "Blah blah blah: Something else"

Should do the trick.

Alternatively you could have

$code = "1" . $code;

// and

print (" Blah blah blah: $$code "); // Variables somehow merge as one

Anyhow, <a style='text-decoration: underline;' href="http://au2.php.net/variables.variable" target="_blank">http://au2.php.net/variables.variable</a> is a fairly good reference
on how to generate variables on the fly.
