Unicode String Issue
I am storing some unicode characters "лфи" in a char array.
When I view(x/30s <variable name>) the values in gdb it show me something like:
0x80ac47c: "?\004>\004 "
0x80ac482: "A\0048\004;\004L\004D\004>\004=\004:\0045\004/"
Why it is happening so and what are these \004 representing?

Hi,
I was trying to do a string comparison using if. However, the comparison result is getting treated as a executable statement. I'm not sure where I'm making the mistake!

$ if ; then echo 'Got It!'; fi;

DESCRIPTION
This function moves the result set cursor to the specified field offset. This offset is used by cubrid_fetch_field(3) if it doesn't
include a field offset. It returns TRUE on success or FALSE on failure.
PARAMETERS
o $result

issued.
RETURN VALUES
TRUE on success.

Example #1
cubrid_field_seek(3) example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$req = cubrid_execute($conn, "SELECT event_code,athlete_code,nation_code,game_date FROM game WHERE host_year=1988 and event_code=20001;");
var_dump(cubrid_fetch_row($req));
cubrid_field_seek($req, 1);
$field = cubrid_fetch_field($req);
printf("

");
printf("%-30s %s
", "name:", $field->name);
printf("%-30s %s
", "table:", $field->table);
printf("%-30s "%s"
", "default value:", $field->def);
printf("%-30s %d

printf("%-30s %d
", "numeric:", $field->numeric);
