This is a sample for PHP4 b3. How come these errors occours?
$j and $k should be equal but they are not. only $j works. should it really be this way?
in the php3-way you didn't need to cast.

-- CUT --
<?
$sql = "select * from linkdb_intresse where id<10";
$res = sybase_query($sql,$conn);
	
$i=0;
while ($rs = sybase_fetch_array($res))
{
	if ($i++ == 0) {
		$j = (string) $rs[1];
		$k = $rs[1];
	}
	echo $j.", ".$k."<BR>";
	// $j and $k should be equal but they are not. only $j works. should it really be this way?
	// in the php3-way you didn't need to cast.
