mac环境下使用vscode调试php无法执行

Question

刚开始学习php，操作环境：mac OS 10.15.7 PHP 7 mac系统自带Apache和PHP
然后安装了vscode，想通过vscode进行调试，但是按F5开始调试后，下一步按钮是灰的，无法继续执行，不知道原因在哪里，还请指明下，谢谢。

launch.json是自动生成的，没有修改。

launch.json配置

    // 调试分两种模式：
    // 1、编辑器内运行调试：先执行 Listen for Xdebug 然后执行 Launch currently open script
    // 2、浏览器访问模式：先执行 Launch Built-in web server， 然后浏览器 http://localhost:8088/testphp.php
