You don't want ' around Check$i because $ has no special meaning
inside of ''. Only \ and ' mean anything special to ''.

Woof.
You could save a WHOLE bunch of trouble making a change (below) and
doing:
$names = $_POST['names'];
$emails = $_POST['emails'];
$checks = isset($_POST['checks']) ? $_POST['checks'] : array();
foreach($names as $i => $name){
$email = $emails[$i];
$check = isset($checks[$i]);
echo "$name: $email ($check)<br />\n";
}
Even so, you sure don't need eval() even if you want to keep
everything else the same:
$name = $_POST["name$i"];
$email = $_POST["email$i"];
//HTTP doesn't send anything for un-checked checkboxes.
$check = isset($_POST["check$i"]);

Change this to:

You may not even need this any more...
The arrays are going to be as big as they need to be, and no bigger.
Like a woman's skirt should be. :-)
