强大的现代PHP高级调试工具Kint · Spring Boot 技术栈

## 概述 Kint是一个类似于`var_dump()`的PHP变量调试工具，但提供了更多高级功能，如键盘控制、搜索、访问路径提示和自动数据解析。支持JSON结构的展开和搜索，提供访问特定字段所需的代码片段。 ## 安装 ``` composer require kint-php/kint --dev ``` ## 使用 ### 简单打印 ``` <?php /** * @desc 简单使用 * @author Tinywan(ShaoBo Wan) */ declare(strict_types=1); require '../vendor/autoload.php'; d('开源技术小栈'); ``` 打印输出 ![](https://img.kancloud.cn/d3/e8/d3e84dd7c258463fce32c583f77d6d23_736x113.png) ###
