Description:

Select data from mssql, and get length of the filed value by using function strlen(), but i got the same output '40', following is field info and smaple code.



Reproduce code:
---------------
name utName (char) 40

$dbh = @mssql_connect($tnserver_ipaddr, $tnserver_user, $tnserver_passwd);
if ($dbh) {
	$room_num = GetRoomNum();
	mssql_select_db("this");
	$sql = "SELECT * FROM [dbo].[HotelFolioView] WHERE (RoomNo = '$room_num')";
	$ret = mssql_query($sql);	

	while ($row = mysql_fetch_array($ret)) {
		print strlen($row['name']).'\r\n';
	}

	mssql_free_result($ret);
}

Expected result:
----------------
4
7
12
8
....
different length

Actual result:
--------------
40
40
40
40
....
