Re: RESEND : Fix for $DOCUMENT_ROOT in ISAPI module for IIS servers on Windows system

Is this still a problem? Has this been fixed? Andi At 01:19 PM 8/4/00 -0400, Comeau, Michel wrote:

Hello everyone,

        I'm resending this fix since no-one seems to be taking care of entering it

in the CVS and i personnaly can't do it. There was a small mistake i made so use this one instead of the previous one. Can someone check this fix and enter it in CVS please ? If there are issues just contact me. darkwing@videotron.ca

        This is my first Fix submission and i'm sure its not a big deal. The reason

i mention it is that i believe that this fix should be checked carefully as i am very new to the OSS and PHP environments.

        I took the time to verify with a unix/apache user and when he echoes

$DOCUMENT_ROOT, it's reporting the root of the virtual folder he is in.

        The fix should probably apply to PWS too but i havent verified it since i

don't have any PWS installed here. I also cannot garantee that i'm using the correct fonctions but it seems to work for me. Feel free to fix whatever mistake i may have made. Specs & Test Case: NT4 SP5 server on local intranet with TCP/IP. IIS4 with 2 webs on 2 different IP's. (168.192.0.11 & 168.192.0.12) Web1 is HELPER located in d:\wwwroot Web2 is SHOPPER located in d:\wwwshop I have entries in LMHOSTS on remote Win2K to identify both. created /test.php in both webs containing : <? echo $DOCUMENT_ROOT; ?> the current output is : nothing, blank, nada, niet, white screen of emptyness for both webs :-) with the fix, the output is : for http://helper/test.php : d:\\wwwroot\\ for http://shopper/testp.php : d:\\wwwshop\\ HOW I FIXED IT: After having done lots of research in the code and trying to figure out where $DOCUMENT_ROOT was defined kinda showed me it was not defined properly. I still can't figure out where it was defined/initialized in the 4.0.1pl2 source code. It seemed to only be define for the CGI version of PHP. I've also taken the time to verify how apache server were handling $DOCUMENT_ROOT by having a IRC user run my test scripts on his server with 2 different subwebs and he got the expected result. Meaning 2 different system paths. THE SOURCE CHANGE: I have changed only 1 file to achieve my results: sapi/isapi/php4isapi.c remember that i changed 4.0.1pl2 version of it. function : sapi_isapi_register_server_variables() ... around line 307 ----------------------------------------------------------------------- static void sapi_isapi_register_server_variables(zval *track_vars_array ELS_DC SLS_DC PLS_DC) {
