sybase_fetch_array returns a single space instead
of empty strings.

example:
1, sql commands
create table test (name text)
go
-- inserting an empty string
insert into test ('')
go

2, php script:
# first connect, select...
$query  = "SELECT * FROM test";
$rc = sybase_query($query, $link);
while ($a = sybase_fetch_array($rc)) {
        printf("<TT>'%s'</TT><BR>\n", $a['name']);
}

3, output of this script:
' '
(one space)

Change printf() to var_dump($a)
What result do you get?

Has any progress been made on this bug report?

This is the proper behavior. Sybase is at fault here,
not PHP. Try the following from isql to see this:
create table test (name varchar(15) null)
go

insert test values ("")
go

insert test values (NULL)
go

select * from test
go

select 'x'+name+'x' from test
go

(Thanks to dean.bennett@home.com for the answer
and test case.)
