What potential issues can arise when using COM objects in PHP, especially on a Windows environment?

One potential issue when using COM objects in PHP on a Windows environment is that the COM extension may not be enabled in the PHP configuration. To solve this, you need to enable the COM extension in the php.ini file by uncommenting or adding the line `extension=php_com_dotnet.dll`.

// Enable COM extension in php.ini
extension=php_com_dotnet.dll
