ErrorHandler classes is a powerful wrapper for PHP error-reporting features. It helps when developing new scripts and monitoring sites in production state, too.

ErrorHandler classes has several enhancements (previously known as report layouts):
- SOURCE = prints the source code fragment where the error encountered,
- CONTEXT = prints variable context around error source,
- SILENT mode = suppresses error-messages
- REPLACE page = displays an arbitrary HTML or PHP page in case of error (useful in production state),
- LOGGING = log errormessages wherever you want (multiple destination also allowed),
- Autodetecting Target Logging = log target can vary from file to file automatically
- CONSOLE window = error messages will be displayed in a separate browser window not to break up your pretty page design
- Error TRAPPING = catching errors for runtime generated codes

Each report can be enabled, disabled or changed at run-time.
