When you say first row, you mean "obs freq cumFreq", right? If so, the perl code does print this.

In perl, scalar variables begin with a "$" symbol. That's the language grammar. Likewise, perl recognizes an array identifier by "@" as in @myArrVar a hash by "%" as in %myHash.

FBSQL_FETCH_OBJECT(3)							 1						     FBSQL_FETCH_OBJECT(3)

fbsql_fetch_object - Fetch a result row as an object

SYNOPSIS
object fbsql_fetch_object (resource $result) DESCRIPTION
fbsql_fetch_object(3) is similar to fbsql_fetch_array(3), with one difference - an object is returned, instead of an array. Indirectly, that means that you can only access the data by the field names, and not by their offsets (numbers are illegal property names). Speed-wise, the function is identical to fbsql_fetch_array(3), and almost as quick as fbsql_fetch_row(3) (the difference is insignifi- cant). PARAMETERS
o $ result -A result identifier returned by fbsql_query(3) or fbsql_db_query(3). RETURN VALUES
Returns an object with properties that correspond to the fetched row, or FALSE if there are no more rows. EXAMPLES
Example #1 fbsql_fetch_object(3) example <?php fbsql_connect($host, $user, $password); $result = fbsql_db_query("database", "select * from table"); while ($row = fbsql_fetch_object($result)) { echo $row->user_id; echo $row->fullname; } fbsql_free_result($result); ?> SEE ALSO
fbsql_fetch_array(3), fbsql_fetch_row(3), fbsql_fetch_assoc(3). PHP Documentation Group FBSQL_FETCH_OBJECT(3)
