I am trying to using ODBC from my PHP application to connect to (remote or local) database (MySQL for this step). I reinstalled RHEL4 and did a install everything. After install, I found out php-odbc and unixODBC are all installed and unixODBC is read to use. I brought up ODBCConfig and added the DSN entry to connect to MySQL localhost. When I try to do - isql -v myDSN from command line , it works well, I can get the data from the local MySQL database. But then when I tried to do it from a php test script using odbc_connect() function, it does not work at all. My guess is: PHP can not communicate with unixODBC. How do I make php-odbc to talk to unixODBC? Can anyone who configured ODBC on RHEL4 (I don't use Postgre DB) get me some advise? Thanks for your help! CZ.
