#45652 [Bgs]: Empty string replaced with blank character

ID: 45652 User updated by: dsauneuf at guillemot dot fr Reported By: dsauneuf at guillemot dot fr Status: Bogus Bug Type: MSSQL related Operating System: Windows PHP Version: 5.2.6 New Comment: As I told you it is working fine under fedora / apache / freetds, and this is running with the SAME mssql database. If you are compting the number of character in an empty string, the result cannot be something different than 0, as it is the definition of the empty string ! So the result is wrong. Now, it can have something to see with either php.ini or the api ntwdblib.dll, or even the way the API is used by PHP, but it cannot be the expected behavior. It is not how MSSQL works either. If this has been submitted *many* times already, can you please provide me with the resolution brought to those case ?

An existing bug report already describes this very problem. Even if you feel that your issue is somewhat different, the resolution is likely to be the same. Thank you for your interest in PHP. This has been submitted *many* times already, and it is also expected behavior. It\'s simply how MSSQL works. ------------------------------------------------------------------------ [2008-07-29 10:43:39] dsauneuf at guillemot dot fr Description: ------------ Empty string turned into a blank character. ----------- Running a php site under windows 2003 / IIS / ntwdblib.dll (2000.80.2039.0) to access an SQL server 2000 database. Same thing under Windows XP / IIS / ntwdblib.dll. Works fine under fedora / apache / freetds. Denis Reproduce code: --------------- $sql=" select '' "; $res_id=mssql_query($sql)or die ("Database Error"); $row=mssql_fetch_row($res_id); echo strlen($row[0]); Expected result: ---------------- Should return 0. Actual result: -------------- Returns 1. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45652&edit=1
