A few things that I've run into so far: Make sure that your INFORMIXDIR environment variable is set. Apache would segfault on my systems when I tried to use any of the informix functions otherwise. I added a line to my apachectl script just to be sure. Ifx_connect() doesn't take quite the same parameters as mysql_connect(). The server you're connecting to is specified via either the INFORMIXSERVER environment variable or one of the ifx default settings in your php.ini. (In either case, it's a pointer to an entry in your INFORMIXDIR/etc/sqlhosts, not a hostname.) Ifx_connect() also expects the database name that you're connecting to. Obviously, in light of the above, there is no ifx_select_db(). Ifx_num_rows() doesn't do the same thing as mysql_num_rows(). It counts the number of rows that you've viewed from the result set, not the total number of rows returned. If you use mysql_fetch_array(), the equivalent Informix function is ifx_fetch_row(). --- Mark Roedel | "Blessed is he who has learned to laugh Systems Programmer | at himself, for he shall never cease LeTourneau University | to be entertained."
