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>";
