IIS6 Application Framework support

Common Gateway Interface (CGI) for CGI and PHP applications Benefits

Very simple to implement and use – single-threaded execution

Disadvantages Poor performance due to high process creation cost Creates and passes request data to a new CGI process Waits for CGI process to produce response Shuts down CGI process

IIS6 Application Framework support

Internet Server Application Programming Interface (ISAPI) Benefit of ISAPI

Can be extremely fast when written correctly

Disadvantage of ISAPI

Must be thread-safe (many PHP extensions are not!)

Requires development in C++

PHP Setup

Per-site PHP configurationConfiguring FastCGI process pool

<fastCgi> <application fullPath="C:\PHP\php-cgi.exe" arguments="-d my.website=website1"> <environmentVariables> <environmentVariable name="PHPRC" value="C:\WebSites\website1" /> </environmentVariables> </application></fastCgi>

Combination of fullPath and arguments uniquely identify FastCGI process pool definition

PHPRC environment variable contains path to the php.ini file

IIS Extensions

Mod_rewrite support for URL rewriting

SQLServer 2008

Express version with Management Studio Free (as in beer) download

MySQL .NET drivers (data import/export)

Open source: Microsoft SQLServer Driver for PHP
