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 webservers
read the note about
subrequests.
To install PHP as a CGI handler, do the following:
Copy php4ts.dll to your systemroot
(the directory where you installed Windows)
Make a file association from the command line.
Type the following two lines:
assoc .php=PHPScript
ftype PHPScript=c:\php\php.exe %1 %* |
In the Netscape Enterprise Administration Server create
a dummy shellcgi directory and remove it just after (this
step creates 5 important lines in obj.conf and allow the
web server to handle shellcgi scripts).
In the Netscape Enterprise Administration Server create
a new mime type (Category: type,
Content-Type: magnus-internal/shellcgi, File Suffix:php).
Do it for each web server instance you want PHP to run

PHP as a CGI executable can be found here:

To install PHP with NSAPI, do the following:
Copy php4ts.dll to your systemroot
(the directory where you installed Windows)
Make a file association from the command line.
Type the following two lines:
assoc .php=PHPScript
ftype PHPScript=c:\php\php.exe %1 %* |
In the Netscape Enterprise Administration Server create
a new mime type (Category: type,
Content-Type: magnus-internal/x-httpd-php, File Suffix: php).
Edit magnus.conf (for servers >= 6) or
obj.conf (for servers < 6) and add the following:
You should
place the lines after mime types init.
Init fn="load-modules" funcs="php4_init,php4_execute,php4_auth_trans" shlib="c:/php/sapi/php4nsapi.dll"
Init fn="php4_init" LateInit="yes" errorString="Failed to initialise PHP!" [php_ini="c:/path/to/php.ini"] |
(PHP >= 4.3.3) The php_ini parameter is
optional but with it you can place your
php.ini in your webserver config directory.
Configure the default object in obj.conf
(for virtual server classes [Sun Web Server 6.0+] in
their vserver.obj.conf):
In the <Object name="default">
section, place this line necessarily after all 'ObjectType'
and before all 'AddLog' lines:
Service fn="php4_execute" type="magnus-internal/x-httpd-php" [inikey=value inikey=value ...] |
(PHP >= 4.3.3) As additional parameters you can add some special
php.ini-values, for example you
can set a docroot="/path/to/docroot"
specific to the context php4_execute
is called. For boolean ini-keys please use 0/1 as value,
not "On","Off",...
(this will not work correctly), e.g.
zlib.output_compression=1 instead of
zlib.output_compression="On"
This is only needed if you want to configure a directory that only consists of
PHP scripts (same like a cgi-bin directory):
<Object name="x-httpd-php">
ObjectType fn="force-type" type="magnus-internal/x-httpd-php"
Service fn=php4_execute [inikey=value inikey=value ...]
</Object> |
After that you can configure a directory in the Administration server and assign it
the style x-httpd-php. All files in it will get executed as PHP.
This is nice to hide PHP usage by renaming files to .html.
Restart your web service and apply changes
Do it for each web server instance you want PHP to run
Note:
The stacksize that PHP uses depends on the configuration of the webserver. If you get
crashes with very large PHP scripts, it is recommended to raise it with the Admin Server
(in the section "MAGNUS EDITOR").
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 webserver
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 3.x way with
getenv() or a similar way (register globals to
environment, $_ENV). You would only get the environment
of the running webserver without any valid CGI variables!
Note:
Why are there (invalid) CGI variables in the environment?
Answer: This is because you started the webserver process from the admin server
which runs the startup script of the webserver, you wanted to start, as a CGI script
(a CGI script inside of the admin server!). This is why the environment of
the started webserver has some CGI environment variables in it. You can test
this by starting the webserver not from the administration server. Use
the command line as root user and start it manually - you will see
there are no CGI-like environment 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 |
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...] |
where
XXX is the HTTP error code. Please delete
any other
Error directives which could interfere with yours.
If you want to place a page for all errors that could exist, leave
the
code parameter out. Your script can get the HTTP status code
with
$_SERVER['ERROR_TYPE'].
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...] |
For both error and directory listing pages the original URI and
translated URI are in the variables
$_SERVER['PATH_INFO'] and
$_SERVER['PATH_TRANSLATED'].
The NSAPI module now supports the nsapi_virtual() function
(alias: virtual())
to make subrequests on the webserver and insert the result in the webpage.
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" |
where
XX is the correct DLL version number.
To get it, look in the server-root for the correct DLL name. The
DLL with the biggest filesize is the right one.
You can check the status by using the phpinfo() function.
