Varaible Syntax

[Garry Jones]

I need to nest a variable into a variable name. Having problem with syntax
Simply put

$dtet is "col"
and $dn can be "blue" or "red"

How do I get the following to work?

$dtet+$dn = $_POST["dtet$dn"];

So that the result is either a variable called '$colblue' with a value of
'colblue' or a variable called '$colred' with a value of 'colred'

Thanks for any help in this matter.

Variable variables:
http://uk.php.net/manual/en/language...s.variable.php

${$dtet . $dn} = "whatever";

But you may want to consider using associative arrays instead, unless you're
forced to write it like this to interface with existing code.

Great thanks for that.

Yes, I realised after I posted that its an array. Sometimes the penny drops
after you hit the enter button. Still, I like your solution. Cheers!
