sybase and php

I have a problem when using php to connect ASE via OpenClient. But I dont know where would be appropriate for me to post this message. Anyway, I did, sorry for any inconvenience caused. I configured a machine with php, pws and open client. Then the php scripting engine seems working fine. And then I created a file named "sybase.php" to test the connection between the php, open client and ASE. However, the return shows that there is something wrong with the ASE. Afterward, I searched the manuals.sybase.com almost entirely for an answer about the error message. But I got nothing, would someone can help to me to solve it. Thanks. The following shows that content of the sybase.php <?php $connect=sybase_connect("TEST","sa", "") or die ("Could not connect to the sybase server!"); $selectdb=sybase_select_db("mydb",$connect) or die ("could not select db"); $clssybase=sybase_close($connect) or die ("Cound not close sysbase database server"); ?> The following shows the content of the error message. Warning: Sybase: Server message: Changed database context to 'master'. (severity 10, procedure N/A) in D:\Inetpub\wwwroot\cgi-bin\sybase.php on line 4 PHP has encountered an Access Violation at 01FA03B3 Thomas ===== Tom mailto:tomcwh@bigfoot.com __________________________________________________ Do You Yahoo!?
