Php Debugbar - depura aplicaciones PHP en el…

Este proyecto es una barra de herramientas de depuración de PHP y inspector de tiempo de ejecución que proporciona una interfaz basada en navegador para monitorear métricas del sistema, uso de memoria y tiempo de ejecución durante el desarrollo web. Funciona como un monitor de rendimiento de aplicaciones y herramienta de diagnóstico, capturando datos en tiempo real y el estado de la aplicación para visualizar el ciclo de vida de ejecución de PHP.

La herramienta se distingue por su capacidad de persistir datos de depuración a través de múltiples solicitudes, permitiendo el seguimiento del historial de solicitudes y el archivo de sesiones anteriores. Soporta la inspección de solicitudes AJAX y gestiona la persistencia de datos durante redirecciones para garantizar que la información de diagnóstico esté disponible a través de cargas de página asíncronas y secuenciales.

El sistema cubre capacidades de observabilidad amplias, incluyendo recolección automatizada de métricas de tiempo de ejecución, registro de mensajes personalizados y el renderizado de variables complejas como volcados HTML interactivos. Utiliza una arquitectura modular con colectores para la agregación de datos, abstracción HTTP basada en drivers y un sistema de almacenamiento basado en interfaces para gestionar cómo se escriben y recuperan los datos de depuración.

La barra de herramientas se integra en las páginas web mediante la inyección de activos de JavaScript y HTML de enlace tardío.

Features

PHP Application Debuggers - Provides a browser-based interface for monitoring real-time system metrics and application state during the development process.
Browser Debugging Toolbars - Implements a browser-based diagnostic toolbar for inspecting AJAX requests and application state.
Data Persistence and Storage - Saves collected application data to external storage, such as files or databases, for analysis across multiple requests.
PHP Runtime Data Collectors - Captures and stores runtime data such as logs and variables for real-time review in a browser-based interface.
Runtime Variable Inspectors - Provides a comprehensive system for collecting and persisting PHP environment data and runtime variables across requests.
Framework Debugging Toolbars - Ships a browser-integrated toolbar that captures and displays real-time PHP application metrics, memory usage, and execution time.
Runtime Performance Profiling - Tracks memory usage, execution time, and database queries to identify performance bottlenecks in a PHP environment.
Runtime State Visualizers - Displays real-time system information and application data in a browser-based bar for development.
Debug Data Visualizers - Renders a browser-based interface showing real-time system information and request metrics.
Custom Metric Collectors - Enables the creation of custom collectors to capture specific runtime metrics and define associated interface widgets.
System Metrics Collection - Collects native system-level performance metrics, database queries, and memory usage.
Metric Collection - Gathers quantitative performance data including memory usage and execution time.
Request History Archives - Saves and retrieves data from previous requests to compare performance or debug recurring issues across sessions.
Asset Injection - Injects JavaScript and HTML into the final page output to render the debug toolbar without modifying application templates.
Cross-Request Debug Persistence - Stores collected debug data in a session or storage mechanism to be displayed after a redirect.
Debug Session Managers - Stores and switches between different sets of debugging data to toggle the viewed context.
Debug History Retrievers - Opens and displays previously stored sets of collected application data via a dedicated URL handler.
AJAX Debug Data Polling - Retrieves debug information for AJAX requests by fetching stored data via a dedicated server-side handler.
HTTP Session and Header Abstractions - Provides a driver interface to manage sessions and headers across different environments, removing reliance on native language mechanisms.
Custom Storage Handlers - Supports implementing custom storage handlers through a defined interface to control how debug data is written and retrieved.
Driver-Based Service Abstractions - Employs a driver interface to decouple HTTP header and session management from the native PHP global state.
Request-to-Debug-Data Mappings - Assigns unique lexically ordered identifiers to requests to map stored debug data to specific browser sessions.
Storage Abstractions - Defines a common storage interface to decouple debug data persistence from the underlying file system or database.
Application Performance Monitoring - Provides a development tool for visualizing system metrics, database queries, and request data during the PHP execution lifecycle.
Custom Debug Logging - Enables adding manual text messages to the debug interface to track application flow and state changes.
Application Diagnostics - Visualizes complex variables and application state through interactive HTML dumps and custom data collectors.
Observability Data Aggregators - Aggregates real-time system and application metrics via modular collectors for unified display.
Debug Widget Mappings - Links collected data sets to specific browser interface components through a configurable mapping of tabs and icons.
Interactive Variable Dumps - Converts complex variables into interactive, searchable HTML dumps with configurable depth.
AJAX Debug Data Transport - Sends debug information via headers or storage handlers to be displayed during asynchronous requests.
AJAX Request Diagnostics - Captures and displays debugging information for asynchronous requests to ensure background processes function.
