How to Install PHP5 IIS 6 Permissions
The PHP hypertext preprocessor is a Web scripting language and runtime used for generating dynamic content. Microsoft's IIS 6 Web server can serve Web pages generated from PHP on a website if PHP is installed on the same server, IIS is configured to use it and the proper permission statements are set. FastCGI impersonation is recommended for PHP. Impersonation allows PHP to run its scripts on behalf of the normal IIS Web server, ensuring PHP5 has proper permissions.

Tips & Warnings
Use Windows Explorer to grant file permissions to the "IUSR" account in a file or folder's properties window. The IUSR account has no permissions by default, and it needs read permission on every file PHP needs to access. If PHP needs to be able to write files, the IUSR account needs write permissions to those files or folders.
