PHP + Apache + ODBC on linux

Hi to all!! I have a problem and i think maby somebody can help me. I have an MS Sql server on a Windows 2000. I have a PHP web in a linux debian. Im trying to access to the MS SQL server through unixodbc. Unixodbc works well becouse y test it under linux , with isql and sqsh, and i know that it works. in my PHP code I load the odbc module with dl('odbc'), and it works, but the problem is that when i do odbc_pconnect("mydsn","myuser","mypasswd"); y have an error like this: Warning: SQL error: [unixODBC] Could not find DSN in odbc.ini, SQL state 08001 in SQLConnect in /path/to/my/page.php on line XX Warning: Supplied argument is not a valid ODBC-Link resource in /path/to/my/page.php on line XX When i test the odbc with isql under linux, i think that isql find an ..odbc.ini under $HOME the file is like this: [ODBC Data Sources] cdr2 = FreeTDS [cdr2] Servername = 192.168.129.6 TraceFile = /tmp/odbc.log Driver = /usr/lib/odbc/libtdsodbc.so Description = logs del call manager. DSN = cdr2 DB = CDR User = myuser Password = mypasswd Port = 1433 [Default] Driver = /usr/lib/odbc/libtdsodbc.so and i think that the problem is that apache user dont find this file. My apache user is www-data, and i try to copy an .odbc.ini file to this user $HOME, but dont works... the conclusions are: 1º ODBC works 2º I have PHP compiled with ODBC support. 3º other users with an .odbc.ini file under $HOME can access to ODBC. but the problem is still there :( so my question is: how can i access from PHP on debian to a well configured ODBC ? thanks in advance!!
