PropelException

PropelException is a base exception class used within the Propel ORM framework. It serves as a general-purpose exception for errors that occur during the operation of Propel. When an issue arises within Propel's data access layer, such as a database connection problem, a query execution error, or an issue with object mapping, a PropelException or one of its more specific subclasses is typically thrown.

This class is designed to provide a consistent way to handle errors within Propel applications. Developers can catch PropelException to gracefully manage any problems that might arise when interacting with the database through Propel. By extending PHP's built-in Exception class, PropelException inherits standard exception handling capabilities, including message, code, and stack trace information.

Subclasses of PropelException exist to categorize different types of errors more precisely. For instance, PropelDatabaseException might be thrown for database-specific issues, while PropelFieldException could indicate problems with specific data fields. This hierarchical structure allows for more granular error handling, enabling developers to react differently to various error scenarios. Understanding PropelException is fundamental for debugging and maintaining applications built with the Propel ORM.
