having problems combining to numbers

[Anon]

"$year" & "1000"
that's my string. that returns a result of 0000. the $year variable in this case is 2002. so why
I can add the two together, but that's not what I need to do. the "1000" will be a variable later, and I want to combine the two variables, not add them. I need a string of numbers.

seems like a stupid question. any help?

<?
$year = 2002;
$num = 1000;
$year .= ":" . $num;

echo $year . "<br>";

$values = explode(':',$year);
print_r($values);
?>
