Laravel is a popular PHP framework that provides developers with a wealth of features and tools to create efficient, secure, and reliable web applications. When developing Laravel applications, errors and exceptions are inevitable. In order to better manage these errors and exceptions, Laravel provides a set of error code definitions, which help developers better organize and handle errors, thereby improving the reliability and maintainability of applications.
The following are Laravel's common error codes and their definitions:
100 Continue: The server has received the request and does some processing, but still requires the client to send the remaining requests. This status code is for the HTTP/1.1 protocol.
101 Switching Protocols: Indicates that the client wants the server to upgrade the protocol, such as upgrading from HTTP/1.0 to HTTP/1.1.
200 OK: Indicates that the request has been successfully processed.
201 Created: Indicates that the request has been successfully processed and the server has created some resources.
202 Accepted: Indicates that the request has been accepted but has not yet been processed by the server.
203 Non-Authoritative Information: Indicates that the server has successfully processed the request, but the returned entity contains some information that is not from the original server.
204 No Content: Indicates that the server has successfully processed the request but did not return any content.
205 Reset Content: Indicates that the server has successfully processed the request, but requires the client to reset the view.
206 Partial Content: Indicates that the server has successfully processed part of the request and returned part of the content.
300 Multiple Choices: Indicates that the entity returned by the request can be accessed from multiple locations.
301 Moved Permanently: Indicates that the resource has been permanently moved to a new location.
302 Found: Indicates that the resource has been temporarily moved to a new location.
303 See Other: Indicates that the entity returned by the request can be obtained in another URI.
304 Not Modified: Indicates that the resource has not been modified and can be obtained directly from the cache.
307 Temporary Redirect: Similar to 302, but clients using POST requests should not change the request method.
400 Bad Request: Indicates that the request sent by the client is invalid.
401 Unauthorized: Indicates that the client requires authentication to access resources.
402 Payment Required: Indicates that the requested resources require payment.
403 Forbidden: Indicates that the client does not have permission to access the requested resource.

406 Not Acceptable: Indicates that the requested content type does not match the content type that the server cannot handle.
407 Proxy Authentication Required: Indicates that the client does not have the proxy authentication information required to access the requested resource.
408 Request Timeout: Indicates that the request has timed out.
409 Conflict: Indicates that the request conflicts with the current status of the resource.
