PHP's ErrorException class allows developers to explicitly throw and handle errors such as Notices or Warnings, which would otherwise be ignored during execution. Extending from the Exception class, ErrorException is useful when a Warning needs to be treated as a failure that should halt or redirect script execution. For example, attempting to access a non-existent file with the file_get_contents() function usually generates a Warning, but can be managed using an error handler function to throw an ErrorException instead. This approach allows developers to treat such warnings as regular exceptions, providing more control over script execution. Additionally, tools like Rollbar offer automated solutions for tracking, analyzing, and managing errors in real-time, which can enhance confidence when deploying production code by simplifying error monitoring and triaging.
