[PHP] can I call a variable... using variables?

[Joseph Szobody]

So here's what I'm trying to do:

I have a form submitting dozens of variables called var1, var2, var3, ...... and on 
and on.

I want to check the value of each of these variables:

for($i = 1;$i < 100; $i++) {
  if($var$i > 0) 
    echo "Yup. $var$i is greater than 0";
}

I get a parse error when trying to run this code. Can I not use $i to call the $var1, 
$var2, etc. variables? Is there another way of doing this?

Thanks,

Joseph
