What are the potential issues with integrating PHP as an ISAPI module on IIS?

One potential issue with integrating PHP as an ISAPI module on IIS is that it may not be properly configured to handle PHP scripts. To solve this, you can update the IIS configuration to map PHP file extensions to the PHP ISAPI module.

<configuration>
  <system.webServer>
    <handlers>
      <add name="PHP" path="*.php" verb="*" modules="IsapiModule" scriptProcessor="C:\php\php-cgi.exe" resourceType="File" />
    </handlers>
  </system.webServer>
</configuration>
