## What it is
The Symfony ErrorHandler component provides tools to manage errors and ease debugging PHP code, converting PHP errors and notices into exceptions and rendering debug error pages. It is a standalone Composer-installable library used by many major PHP projects.

## Use cases
- turn PHP errors and warnings into catchable exceptions
- show detailed debug error pages during development
- wrap code so any failure throws an exception even with the @ silence operator
- render custom generic error pages in production
- improve class error messages with DebugClassLoader

## When to choose
- you want robust, battle-tested error handling in any PHP project
- you need nice exception pages while debugging
- you want errors converted to exceptions consistently across legacy code

## When to avoid
- you need application performance monitoring or APM rather than error handling
- your framework already provides its own error handling layer you prefer

## Facets
- artifact type: library
- maturity: stable
- function: error-handling, logging, developer-tools
- domain: developer-tools, web-development, backend
- platform: php, cross-platform
- tags: symfony-component, exception-handling, debugging, php, error-pages
