Php Debugbar
这是一个 PHP 调试工具栏和运行时检查器，为 Web 开发期间监控系统指标、内存使用情况和执行时间提供了基于浏览器的界面。它作为应用性能监控和诊断工具，捕获实时数据和应用状态，以可视化 PHP 的执行生命周期。
该工具的独特之处在于能够跨多个请求持久化调试数据，从而实现请求历史记录追踪和过往会话归档。它支持检查 AJAX 请求，并在重定向期间管理数据持久化，确保在异步和顺序页面加载过程中均可获取诊断信息。
该系统涵盖了广泛的可观测性功能，包括自动运行时指标收集、自定义消息日志记录，以及将复杂变量渲染为交互式 HTML 转储。它采用模块化架构，包含用于数据聚合的收集器、基于驱动程序的 HTTP 抽象，以及用于管理调试数据读写的接口驱动存储系统。
该工具栏通过 JavaScript 和 HTML 的后期绑定资产注入集成到网页中。
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.
