I am trying to connect to Informix 7.1/Solaris from PHP 4.3.6/Apache 1.3.29 on a windows box. I have tried both ifx_connect and odbc_connect with no luck. I have a ODBC connection to the Informix/Solaris set up from that box and it works, I have used it to look thorough the DB tables. I have the save setup talking to a remote MySQL with no problem.
For ifx_connect my error is
ifx_connect(): E [SQLSTATE=IX 001 SQLCODE=-1829]
For odbc_connect my error is
odbc_connect(): SQL error: Specified driver could not be loaded due to system error 127 (INFORMIX 3.34 32 BIT)
