Bit short on comments and tips bout this one so head down to mysql_fetch_fields where the concept is the same. I seemed to get an infinite loop over there using the $i counter tho, so I used a for loop instead.
The list of properties you can get from what I've called $info is in the example to the mysql equivalent.
//start of an example to print out column headings
echo "<table><tr>";
$numfields=sybase_num_fields($query);
for ($f=0;$f<=$numfields;$f++){
$info = sybase_fetch_field($query);
echo "<td> $info->name </td>";
}
echo "</tr><tr>";
