What are the necessary settings in PHP.ini and IIS server for successful file uploads in PHP?

When uploading files in PHP, it is important to ensure that the PHP configuration settings in php.ini and the IIS server settings are properly configured to allow file uploads. In php.ini, the `upload_max_filesize` and `post_max_size` directives should be set to accommodate the size of the files being uploaded. Additionally, the `file_uploads` directive should be set to `On` to enable file uploads in PHP. In the IIS server settings, the maximum allowed file size for uploads should be configured to match the settings in php.ini. 

// Set PHP configuration settings in php.ini
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '20M');
ini_set('file_uploads', 'On');

// Set IIS server settings for file uploads
// Maximum allowed file size for uploads should be configured in IIS server settings
