PHP 4.x Win32 Documentation

Requirements Support Installation Adding Extensions

PHP 4.0 for Windows comes in two flavours - a CGI executable (php.exe), and an ISAPI module (php4isapi.dll). The latter is new to PHP 4.0, and provides significantly improved performance and some new functionality. However, please note that the ISAPI module is *NOT* yet considered to be production quality. The reason for this is that the PHP ISAPI module uses the thread-safe version of the PHP code, which is completely new to PHP 4.0, and has not yet been tested and pounded enough to be considered completely stable, and there are actually a few known bugs. On the other hand, some people have reported very good results with the ISAPI module, even though we're not aware of anyone actually running it on a production site. In short - your mileage may vary; If you need absolute stability, trade the performance of the ISAPI module with the stability of the CGI executable.

A number of modules are built in by default theres are:

MySQL, ODBC, FTP, Calendar, BCMath, COM, PCRE, Session, WDDX and XML support is *built-in*.
(You don't need to load any additional extensions in order to use these functions.)

Requirements

• Windows 95 or later, Windows NT 4.0 or later
• ISAPI 4.0 compliant Web server required for ISAPI module (tested on IIS 4.0, PWS 4.0 IIS 5.0). IIS 3.0 is *NOT* supported; You should download and install the Windows NT 4.0 Option Pack with IIS 4.0 if you want native PHP

Support.

For questions and help with PHP under Windows, your best bet would be the PHP-Windows mailing list (php-windows@lists.php.net). To subscribe, send an empty message to php-windows-subscribe@lists.php.net.

Windows 95 requires the DCOM update, freely available from: http://download.microsoft.com/msdownload/dcom/95/x86/en/dcom95.exe

Installation

Unlike PHP 3, PHP 4 is divided into several components; Even when you use PHP in its CGI mode, php.exe is no longer a standalone executable, and relies on external DLLs for execution. For this reason, if you install php.exe as a handler for your web server, you must make sure that the DLLs in the distribution exist in a directory that is in the Windows PATH. The easiest way to do it is to copy these DLLs to your SYSTEM (Windows 9x) or SYSTEM32 (Windows NT) directory, which is under your Windows directory. The DLLs that need to be copied are MSVCRT.DLL (it may already exist in there) and PHP4TS.DLL.

Installation Notes for IIS 4.0 and 5.0 - ISAPI method

• Install the DLLs as mentioned above.
• If you wish to change any defaults, copy either the php.ini-dist or php.ini-optimized files into your Windows directory, and rename it to 'php.ini'. You can then modify any of the directives inside it.
• Start the Microsoft Management Console (may appear as 'Internet Services Manager', either in your Windows NT 4.0 Option Pack branch or the Control Panel->Administrative Tools under Windows 2000).
• Right click on your Web server node (will most probably appear as 'Default Web Server'), and select 'Properties'.
• If you don't want to perform HTTP Authentication using PHP, you can (and should) skip this step. Under 'ISAPI Filters', add a new ISAPI filter. Use 'PHP' as the filter name, and supply a path to the php4isapi.dll that is included in the distribution.
• Under 'Home Directory', click on the 'Configuration' button. Add a new entry to the Application Mappings; Use the path the php4isapi.dll as the Executable, supply .php as the extension, leave 'Method exclusions', blank, and check the Script engine checkbox.
• Stop IIS completely (you would have to stop the IIS Administration service for that - stopping it through the Management Console isn't good enough; You can do it by typing 'net stop iisadmin' on a command prompt).
• Start IIS again (you can do it by typing 'net start w3svc' on a command prompt).
• Put a .php file under your Web server's document root and check if it works!

Installation Notes for Microsoft PWS 4.0 - ISAPI method

• Install the php.ini file and the DLLs as mentioned above.
• Edit the enclosed PWS-php4.reg file to reflect the location of your php4isapi.dll. Forward slashes should be escaped, for example:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\w3svc\parameters\Script Map]

".php"="C:\\Program Files\\PHP\\php4isapi.dll"

• In the PWS Manager, right click on a given directory you want to add PHP support to, and select Properties. Check the 'Execute' checkbox, and confirm.

At this point, PWS should have built-in PHP support.

Apache

Stop the Apache Webserver.

• Edit the httpd.conf and put in these lines, modified to your environment:
• Unzip the Package to c:\php, now move php4ts.dll to the windows/system(32) directory, overwritte any older file!

# for the apache module
LoadModule php4_module c:/php/sapi/php4apache.dll
AddType application/x-httpd-php .php4
#for the cgi binary (you can use that one compiled with force cgi redirect too)
ScriptAlias /php4/ "C:/php/"
Action application/x-httpd-php4 "/php4/php.exe"
AddType application/x-httpd-php4 .php

• Copy the php.ini-dist to your sysroot (directory where you installed windows), rename it to php.ini, and
• edit the php.ini to fit your needs.
• Restart the Apache server.

• First make sure that you got atleast Version 2.5
• Edit the Server Properties and select the tab "Mapping"
• From the List select "Associations" and enter the desired extension (".php") and the path to the cgi exe or the isapi dll
• Now select "Content Types" add the same extension ".php" and enter the contenttype:

cgi wwwserver/shellcgi
isapi wwwserver/isapi

• Copy the php.ini-dist to your Systemroot (Directory where you installed windows), rename it to php.ini, and edit it to fit your needs.

Xitami

• Copy the php.ini-dist to your Systemroot (Directory where you installed windows), rename it to php.ini, andedit it to fit your needs.
• Make sure the webserver is running, and point your browser to xitamis admin console (usually http://127.0.0.1/admin), and click on Configuration
• Now navigate to the Filters, and put the extension which php should parse (i.e. .php) into the field File extensions (.xxx)
• In Filter command or script put the path and name of your php executable i.e. c:\php\php.exe
• Press the 'Save' icon
  

Adding Extensions

A few pre-compiled extensions are included in this release. You can load them by adding a line like the following to your php.ini file:

extension=path\to\extension\extension_name.dll

Loading these extensions extends the functionality of PHP to support more functions and protocols.

Note: MySQL support is *built-in* as of PHP 4.0. You don't need to load any additional extensions in order to use the MySQL functions.
