Type casting shouldn't be an issue in this case. For example,
you're not trying to convert alphanumeric characters to int() (which
would actually go to boolean - 0/1), so when trying this case, the
condition is True:
<?
$rowA[] = 54;
$rowA[] = 63;
$rowA[] = 72;
$rowB['54'] = "Y";
$rowB['63'] = "N";
$rowB['72'] = "N";
if($rowB[$rowA[0]]=='Y') { echo "checked.\n"; }
?>
Because of the loose-typecasting nature of PHP (done on purpose),
'54' does, in fact, equal 54, unless otherwise specifically stated.
