What role does the web server play in setting file upload limits in PHP, especially in the context of IIS on a Windows Server?

The web server plays a crucial role in setting file upload limits in PHP, especially in the context of IIS on a Windows Server. By default, IIS has its own file upload limit settings that may override the PHP settings. To ensure that PHP's file upload limits are respected, you need to adjust the configuration settings in both PHP and IIS. 

// Adjusting PHP settings for file uploads
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '25M');

// Adjusting IIS settings for file uploads
// Open IIS Manager
// Select the website you are working with
// Double click on "Request Filtering"
// Click on "Edit Feature Settings" in the Actions pane
// Increase the "Maximum allowed content length" to match your PHP settings
