If you want to capture a list from a POSTed form, then use the array syntax trick instead of enumerated input field names:

This way you need no guessing in PHP, because emails[] becomes an array implicitely then:

print_r($_POST["emails"]);
foreach ($_POST["emails"] as $email) {

For database-escaping just use:

$db_emails = array_map("mysql_real_escape_string", $_POST["emails"]);
// that's an array too
