Consider the differences between my code below and yours. And as far as I
can see, there's no combination higher than eleven, lower than 987 which
doesn't work out.
<?
for ($i = 12; $i < 987; $i++) {
$newI = $i;
settype($newI, "string");
$newI = str_pad($newI, 3, "0", STR_PAD_LEFT);
$digits = $newI[0] + $newI[1] + $newI[2];
$num1 = $newI[0].$newI[1].$newI[2];
$num2 = $newI[0].$newI[2].$newI[1];
$num3 = $newI[1].$newI[0].$newI[2];
$num4 = $newI[1].$newI[2].$newI[0];
$num5 = $newI[2].$newI[0].$newI[1];
$num6 = $newI[2].$newI[1].$newI[0];
$sum = $num1 + $num2 + $num3 + $num4 + $num5 + $num6;
$answer = $sum / $digits;
if ($answer != "222") {
echo $i." does not fit in the scheme.";
}
}
?>
