New Comment:
More than 3 years later (version 4.4.6 tested today) the bug seems to
be still present.
Please, if you don't wan't to consider this issue as a bug, would it be
possible to add a "mssql.trimemptystringspace" option to the mssql
module in order to let developpers choose to activate or not this
feature via init_set() or the php.ini file ?
It would be more efficient than triming all returned row in the PHP
code.
Thanks in advance.
Clement

'' = ' '. Politely, this is a bug. In transact sql and query analyzer
'' is seen as '' but in php '' is seen as ' '. I am using varchar
fields. This surely breaks several lines of code for the empty function
is now useless when selecting '' out of the database. Please reconsider
and look into this item.
Add autotrim to the ini file if this would fix the problem.

hmm this is a bug
i developed a cms first for mysql and the port for postgre with select
database-type works very fine
the last two days i try to get it running with mssql/msde an nothing
works with this damned spaces
if (!empty($image)) echo "<img src=\"" . $image . "\" />"; for example
makes a big shit :-(

If you must make from a space to '' in your PHP script, how can you
distinguish between a "true" space or "faked" space?
All '' and space in the DB are then '' (:-((()

In my opinion this is bug, and is still present on version 4.3.6. This
is not only problem with CHAR, and NCHAR columns but also empty VARCHAR
columns returns space.
Example:
$re = mssql_fetch_row(mssql_query("SELECT CAST('' AS VARCHAR(10))"));
print('--'.$re[0].'--');
// the result is: -- --
// and should be: ----
Because of that I still use PHP4.3.3.

The Protocol have been changed.
Quote from Sybase Doco.
[quote]
The empty string ("") is treated as a single space. In *char* and
*nchar* *not null* columns, the result is a (column-length) field of
spaces.
