按照视频的最后我再dos命令框中测试php -v 无反应

MariaDB [(none)]> show databases;
±-------------------+
| Database |
±-------------------+
| information_schema |
| test |
±-------------------+
2 rows in set (0.01 sec)

MariaDB [(none)]> exit
Bye

C:\tp5Tool\mysql\bin>php -v
’php’ is not recognized as an internal or external command,

提示代码如上，是没有配置环境变量path吗？
Apache 和mysql 都开启
