What are the potential pitfalls of using IIS with PHP compared to Apache?

One potential pitfall of using IIS with PHP compared to Apache is that IIS may not have the necessary modules or configurations set up by default to properly run PHP scripts. This can lead to compatibility issues and errors when trying to execute PHP code on an IIS server. To solve this, you can manually configure IIS to work with PHP by installing the PHP handler and setting up the appropriate mappings in the IIS Manager. 

// Example PHP code snippet for configuring IIS to work with PHP
// Add the following lines to your web.config file in the <system.webServer> section

<system.webServer>
    <handlers>
        <add name="PHP_via_FastCGI" path="*.php" verb="GET,POST,HEAD" modules="FastCgiModule" scriptProcessor="C:\PHP\php-cgi.exe" resourceType="File" requireAccess="Script" />
    </handlers>
</system.webServer>
