We are confusing one another :) I'm not talking
about declaring variables per se, but rather making
sure the variable exists before evaluating it. So:
$var = 'foobar';
if ($var == 'foobar')
That's fine, no need to do declare $var before this
in PHP. My words here simply mean to make sure it exists
before comparing it. (let's not talk about oop)
Your example of $var$i is fine, and will work without
any errors (if I'm following). Btw, you should use
arrays versus this method, arrays kick ass. Sure
doing ${'foo'.$i} or similiar has its purpose but
usually an array will do (please!).
When in doubt, put error_reporting(E_ALL) on top of your
script and go to town.
