preg match help

[FiRe]

Can anyone pls help me write the regex for validating $id using ereg or preg_match?

$id will consist of any number, followed by a ; followed by a 1 or 2. For example:

1283;1
232;1
1932034;2
0018;2
5;1

etc.

Thanks in advanced!

if (preg_match("^[0-9]+;[12]{1}$", $id))
{
echo "A match was found.";
}
else
{
echo "A match was not found.";
}
