Question

Sorry for a misleading title, was hard to explain the problem so short…

So I’ve got a few variables named $exp_lvl1, $exp_lvl2 and so on…

To make it more simple I got $exp_lvl (which just gives an error because it don’t exist and that’s normal in this case) and I got the number needed in a variable $next_exp.

How do I put these together? I have tried $exp_lvl.$next_exp and it didn’t work. How should I do?

I guess you want something like this:

$x = ${$exp_lvl.$next_exp};

Test:

<?php

$exp_lvl = 'var_';
$next_exp = '1';
$var_1 = 'okay';

$x = ${$exp_lvl.$next_exp};
echo $x;

?>
