PHP是在实践中发展迅速并被最多使用的脚本语言；包含了诸如详细的文档、庞大的社区、无数可使用的脚本及支持框架等许多特性。PHP提供的这些特性使得它比Python或Ruby等脚本语言更容易上手。
为构建极具创新乐趣的Web应用，PHP开发人员持续搜寻着有用的工具。在这篇文章中，我收集了开发人员的12个PHP调试工具，它们将有助于开发人员轻松找出并调试应用程序及脚本中的错误。下面的PHP调试工具支持Ajax请求，并包含通用数据采集器和基于堆栈的错误处理器。我希望你能在未来的项目中体会到这个列表的方便和有用之处。
1. Kint
当调试PHP代码时，var_dump()、print_r()和debug_backtrace()是我们最常用的工具。Kint，一个开源软件，一个不需安装的替代者，它提供了更好的调试体验。它巧妙地检测几乎不可读的数据，并将它们定制成规则的输出显示。变量名、文件、行号及包装的函数它全能提示出来。
源码
2. DebugBar
DebugBar是一个自由开源软件，它可以被集成到任何PHP项目用来收集和定位数据。它没有第三方依赖，支持Ajax请求，包含通用数据收集器且集成常见的库。生成的bar是100% JavaScript实现的并被放置在页面底部（像开发工具一样）。新的收集器和视图可以被轻松的添加，并且可以保存或重新运行以前的请求。
源码
3. Pinba
Pinba是一个可作为PHP统计服务使用的开源MySQL存储引擎。它使用收到的数据来分析PHP应用性能并快速定位任何问题。
源码
4. PHPMD
PHPMD是一个易于配置，对PHP原始依赖指标友好的前端。它在你的代码中的寻找多种潜在问题，包括可能的bug、不适合的代码、未使用的参数等。
源码
5. Xde Bug
Xdebug是一个自由开源的用于调试和分析PHP脚本细节的PHP扩展。由于它是一个扩展，所以使用起来很方便，且在编码端只需要很少的设置。它可以提供错误信息中堆栈跟踪和函数跟踪的所有数据，包括用户定义函数的所有参数、函数名、文件名以及行标志。Xdebug还可以提供内存分配、分析信息和代码覆盖率分析的数据。
源码
6. Whoops
Whoops是一个使错误处理和调试更容易的PHP库。这个库提供基于堆栈的错误处理，并且有一个好看的界面。它有一个处理异常的简单API，能够跟踪帧及它们的数据，并可以与任何框架整合（end和Silex已经内置集成）。
源码
7. Krumo
很多PHP开发者使用print_r()和var_dump()对输出难读或未格式化的结果进行调试。Krumo是这些函数的一个替代者，它可以显示任何PHP变量的结构化信息。Krumo运行后，输出会显示成一个围绕PHP变量的可折叠的DHTML树结构。同时，它通过自身把调试过程“关掉”而不是禁用代码里的所有追溯路径的能力加快了调试过程。
源码
8. Php Debugger
调试是发现并修复bug的过程，PHP Debugger是帮助你快速的找到错误并将它们从你的PHP程序中移除的最好的工具。你可以在PHPEd中设置远程调试，通过Wizardand DBG向导中的PHP调试设置开启。
源码
9. Php Debug
PHP_Debug的基本目的是在调试PHP代码时提供援助。
源码
10. Webgrind
Xdebug是最受欢迎的PHP调试扩展之一。它提供了许多有用数据来帮助你在源码中查找bug。
源码
11. PHP_Dyn
PHP_Dyn是有一个优秀的开源PHP调试工具。你可以跟踪函数执行并得到函数参数和返回值的一个输出。
源码
12. MacGDBp
MacGDBp是一个MAC OS上的PHP调试器。它有你所期望的所有特性，是一个包含逐句运行及设置断点等功能的全功能调试器。

Best Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AMThe reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
