刚下载了个PHP工具箱，但是不知道怎么使用，
，
编写的php应该放在保存在哪里呢？是放在网站根目录下的吗？
上图是我将php文件保存在网站根目录下的测试文件，但是浏览器直接输出代码，这是为什么啊？新手求解答，谢谢各位！！
php executable program cannot be opened directly through the browser
The php file is placed in the root directory of the website. Open the address with a browser and enter "localhost/your php file name", and that's it!
