Debug

The Symfony Debug component is a PHP debugging toolkit that converts PHP warnings and notices into exceptions for consistent runtime error handling. It provides a unified error management system by registering a global error handler that intercepts all PHP errors and forwards them to an exception-based pipeline.

The component catches uncaught PHP exceptions and displays detailed stack traces enriched with file, line, and call chain context for developer visibility. It maps PHP error severity levels to corresponding exception types, enabling granular control over how different error conditions are handled during development.

The debugging workflow is integrated through a runtime error-to-exception pipeline that chains error detection, conversion, and exception throwing into a seamless flow. The component also provides an uncaught exception display layer that renders formatted error output for debugging purposes.

    filp/whoops

    13,236View on GitHub↗

    Whoops is a PHP debugging tool and error handler designed to intercept and visualize exceptions and stack traces during application development. It functions as an exception renderer that converts errors into human-readable web pages or machine-readable responses. The project differentiates itself by providing a visual debugging interface with line-highlighted code views and a stack trace visualizer that links directly to source files in a local text editor or IDE. It employs environment-aware response resolution to automatically select between HTML, JSON, XML, or plain text output based on t

    symfony/error-handler

    2,677View on GitHub↗

    This library provides a structured framework for managing runtime failures and debugging within PHP applications. It functions by intercepting native language errors, warnings, and system signals, converting them into catchable, object-oriented exceptions to ensure consistent control flow throughout the application lifecycle. The project distinguishes itself by normalizing raw execution backtraces and providing a transformation layer that standardizes how system failures are reported. It includes specialized tools for monitoring the class loading process, ensuring that dependency resolution i

    This project is a PHP-based framework designed for the automated development of standardized web services. It functions as a backend toolkit that maps internal data models to REST and GraphQL endpoints, providing built-in support for resource management, data serialization, and hypermedia-aware API operations. The framework distinguishes itself through a metadata-driven architecture that uses class-level attributes to automatically derive API schemas, validation rules, and documentation. By analyzing these definitions at runtime, it generates machine-readable specifications and interactive in

    CodeIgniter is an open-source PHP web framework and application toolkit designed for server-side development. It implements a model-view-controller architecture to separate internal data representations from the user interface. The framework utilizes a front-controller architecture to direct all incoming web requests through a single entry point for URI parsing and request dispatching. It includes a dependency injection container to resolve class dependencies and manage the lifecycle of core system components. The toolkit provides capabilities for routing management, database interactions, a
