Description:
------------
I am working on porting phpbb over to DB2, and ran into an error with odbc_fetch_row. When the following SQL is executed:

?SELECT * FROM phpbb_fourms WHERE forum_id = 1?

odbc_fetch_row($result_id, $i) returns false. Where i = 1.

Sending the query to the database returns one row. When I remove the $i from odbc_fetch_row it works perfectly. Also if more than one result is returned there is no problem. Also it seems to only occur when there is a select * or when there is a large number of columns returning a single row. 

I am pretty sure I have experienced this bug since the early 4.0.* days.


Reproduce code:
---------------
$i =  1;
$k = 0;
                    
while(odbc_fetch_row($result_id, $i) && $k < $this->result_numrows[$result_id]){

for($j = 1; $j < count($this->result_field_names[$result_id])+1; $j++){

$this->result_rowset[$result_id][$k][$this->result_field_names[$result_id][$j-1]] = odbc_result($result_id, $j);

}
$i++;
$k++;
}

Expected result:
----------------
Expected odbc_fetch_row($result_id, $i) to return true.

Actual result:
--------------
odbc_fetch_row($result_id, $i) returned false if just one row was selected from the database. If more than one row was selected it returned true and worked fine.

Removing the $i from odbc_fetch_row() fixed the problem. None the less it is still appears a bug. I also verified that the database query does return one result.
