Oh, now I see what you are doing... you could have used
eval("return 'item'.$cnt.;") as well.
However, it would be easier to setup the HTML form to use arrays to
pass. For instance:
<input type="checkbox" name="item[0]" value="1">
<input type="checkbox" name="item[1]" value="1">
<input type="checkbox" name="item[2]" value="1">
<input type="checkbox" name="item[3]" value="1">
<input type="checkbox" name="item[4]" value="1">
<input type="checkbox" name="item[5]" value="1">
Then use something like:
foreach($_POST['item'] as $item_number=>$value){
if(!empty($value))
echo 'item #'.$item_number.' has been checked.<br>'."\n";

This is the way that I usually handle it.
