It is not possible to use PHP cgi with NETSCAPE E.S. 3.51 and INFORMIX because it is imperatively necessary to have INFORMIXSERVER variable in the environment. Alas the environment of scripts cgi is very limited. To be able to use INFORMIX nevertheless, I supplemented the file php.ini by adding a parameter 'INFORMIX.default_server' then I modified the file in order to read this parameter and to place it in the environment Before calling upon 'ifx_connect'. Is it possible to register my modifiaction in a permanent way in PHP?

create a patch file with your changes (diff -u <file name> > <patch name>)  and send it to the PHP mailing lists.

mind you will also want to place the patch here in the bug report, and give a good reason why, and sample script to reproduce the bug you are fixing.

Just wondering..if you set INFORMIXSERVER prior to starting
the webserver, doesn't the webserver inherit the environment?? How are you running PHP? As a NSAPI module
or CGI ? FYI:I just recently committed a huge patch for 
Informix to make it compile and work in threaded

No feedback. Reopen if you still have this problem
with PHP 4.0.7 (soon to be released) or with latest CVS
