What are the differences in PHP behavior when running applications locally versus on hosting servers like Hetzner?

When running PHP applications locally, the configuration settings may differ from those on hosting servers like Hetzner. One common issue is the display_errors setting, which may be enabled locally but disabled on the server. To ensure consistent behavior, it is recommended to set the display_errors setting explicitly in your PHP code.

// Set display_errors to On for consistent behavior
ini_set('display_errors', 1);
error_reporting(E_ALL);
