#112 [PHP]Error message is empty when row number is out of range of cubrid_data_seek method

[Jira Trac]

Test Build: CUBRID 2008 R4.1 (8.4.1.1018) (64bit release build for linux_gnu)
OS: Linux 64
Description:
when the value of $row_number is out of range, the error code is 0 in [cubrid_data_seek()|http://www.php.net/manual/en/function.cubrid-data-seek.php] method.
when the value of $offset is out of range, the error message will appear in [cubrid_move_cursor|http://www.php.net/manual/en/function.cubrid-move-cursor.php] method

Decription in [APIS-109|http://jira.cubrid.org/browse/APIS-109]:
Make the return values of cubrid_move_cursor and cubrid_data_seek consistent with mysql_data_seek

when the row number is out of range,whether the error message need to be consistent with mysql_data_seek

Repro steps:
Repro steps:
First: cubrid_data_seek method
1. execute: php seek_errormsg_test2.phpt
statements in seek_errormsg_test2.phpt
{noformat}
$sql =CREATE TABLE seek_tb(id int, name varchar(10));
cubrid_execute($conn,$sql);
cubrid_execute($conn,insert into seek_tb values(1,'name1'),(2,'name2'),(3,'name3'),(4,'name4'),(5,'name5'));
$req1 = cubrid_execute($conn, SELECT * FROM seek_tb);

//offset is large than range
$mov2=cubrid_data_seek($req1,5);
if(FALSE == $mov2){
printf([002]Expect false [%d] [%s]\n, cubrid_errno($conn), cubrid_error($conn));
}else{
printf([002]Move success\n);
$result = cubrid_fetch_row($req1);
var_dump($result);
}

//offset is less than 0
$mov3=cubrid_data_seek($req1,-1);
if(FALSE == $mov3){
printf([003]Expect false [%d] [%s]\n, cubrid_error_code(), cubrid_error_msg());
}else{
printf([003]Move success\n);
$result = cubrid_fetch_row($req1);
var_dump($result);
}
cubrid_close_request($req1);
{noformat}

Actual result:
error code is 0 and error message is empty.
{noformat}
[002]Expect false [0] []
[003]Expect false [0] []
{noformat}

Second: cubrid_move_cursor method
Statements:
{noformat}
$sql =CREATE TABLE move_tb(id int, name varchar(10));
cubrid_execute($conn,$sql);
cubrid_execute($conn,insert into move_tb values(1,'name1'),(2,'name2'),(3,'name3'),(4,'name4'),(5,'name5'));
$req1 = cubrid_execute($conn, SELECT * FROM move_tb order by id);
//offset is large than range
$mov2=cubrid_move_cursor($req1,7, CUBRID_CURSOR_FIRST);
if(FALSE == $mov2){
printf([002]Expect false [%d] [%s]\n, cubrid_errno($conn), cubrid_error($conn));
}else{
printf([002]Move success\n);
$result = cubrid_fetch_row($req1);
var_dump($result);
}

//offset is less than 0
$mov3=cubrid_move_cursor($req1,-1, CUBRID_CURSOR_FIRST);
if(FALSE == $mov3){
printf([003]Expect false [%d] [%s]\n, cubrid_error_code(), cubrid_error_msg());
}else{
printf([003]Move success\n);
$result = cubrid_fetch_row($req1);
var_dump($result);
}
cubrid_close_request($req1);
{noformat}

Actual result:
Error message is invalid cursor position
{noformat}
