Are there specific server configurations or settings that need to be in place for PHP applications to run smoothly?

To ensure PHP applications run smoothly, it is important to have the correct server configurations and settings in place. This includes ensuring that the server has enough memory allocated to handle PHP scripts, enabling necessary PHP extensions, setting appropriate file upload limits, and configuring error reporting settings.

ini_set('memory_limit', '256M');
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '20M');
error_reporting(E_ALL);
ini_set('display_errors', 1);
