Sun, iPlanet and Netscape servers on Microsoft Windows
This section contains notes and hints specific to Sun Java System Web Server, Sun ONE Web Server, iPlanet and Netscape server installs of PHP on Windows.
From PHP 4.3.3 on you can use PHP scripts with the NSAPI module to generate custom directory listings and error pages. Additional functions for Apache compatibility are also available. For support in current web servers read the note about subrequests.
CGI setup on Sun, iPlanet and Netscape servers
To install PHP as a CGI handler, do the following:

NSAPI setup on Sun, iPlanet and Netscape servers
To install PHP with NSAPI, do the following:
CGI environment and recommended modifications in php.ini
Important when writing PHP scripts is the fact that Sun JSWS/Sun ONE WS/iPlanet/Netscape is a multithreaded web server. Because of that all requests are running in the same process space (the space of the web server itself) and this space has only one environment. If you want to get CGI variables like PATH_INFO, HTTP_HOST etc. it is not the correct way to try this in the old PHP way with getenv() or a similar way (register globals to environment, $_ENV). You would only get the environment of the running web server without any valid CGI variables!
Simply change your scripts to get CGI variables in the correct way for PHP 4.x by using the superglobal $_SERVER. If you have older scripts which use $HTTP_HOST, etc., you should turn on register_globals in php.ini and change the variable order too (important: remove "E" from it, because you do not need the environment here):
variables_order = "GPCS" register_globals = On
Special use for error pages or self-made directory listings (PHP >= 4.3.3)
You can use PHP to generate the error pages for "404 Not Found" or similar. Add the following line to the object in obj.conf for every error page you want to overwrite:
Error fn="php4_execute" code=XXX script="/path/to/script.php" [inikey=value inikey=value...]
Another possibility is to generate self-made directory listings. Just create a PHP script which displays a directory listing and replace the corresponding default Service line for type="magnus-internal/directory" in obj.conf with the following:
Service fn="php4_execute" type="magnus-internal/directory" script="/path/to/script.php" [inikey=value inikey=value...]
Note about nsapi_virtual() and subrequests (PHP >= 4.3.3)
The NSAPI module now supports the nsapi_virtual() function (alias: virtual()) to make subrequests on the web server and insert the result in the web page. The problem is, that this function uses some undocumented features from the NSAPI library.
Under Unix this is not a problem, because the module automatically looks for the needed functions and uses them if available. If not, nsapi_virtual() is disabled.
Under Windows limitations in the DLL handling need the use of a automatic detection of the most recent ns-httpdXX.dll file. This is tested for servers till version 6.1. If a newer version of the Sun server is used, the detection fails and nsapi_virtual() is disabled.
If this is the case, try the following: Add the following parameter to php4_init in magnus.conf/obj.conf:
Init fn=php4_init ... server_lib="ns-httpdXX.dll"
You can check the status by using the phpinfo() function.
