PHP Luminova: Exceptions and Custom Error Codes

Last updated: 2024-08-29 02:30:39

This documentation provides a complete reference for error codes with it's usage descriptions. The ErrorCodes trait in the Luminova framework defines a set of constants that represent various error codes. These codes encompass a wide range of PHP error types, including:

PDO SQLSTATE Codes
MySQL Error Codes
PostgreSQL Error Codes
Custom Error Codes

The AppException class automatically inherits the ErrorCodes trait, granting any exception class that extends AppException access to these error constants defined within the ErrorCodes trait.
