How can server configurations impact the ability to upload files using PHP?

Server configurations can impact the ability to upload files using PHP by setting limits on file size, maximum upload size, and allowed file types. To solve this issue, you can adjust the server settings to allow larger file uploads, increase the maximum execution time, and enable file uploads in the PHP configuration. 

// Increase file upload size limit
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '20M');

// Increase maximum execution time
ini_set('max_execution_time', 300);

// Enable file uploads
ini_set('file_uploads', 'On');
