In our previous article, we took you to understand what a php probe is and what a php probe does. I believe everyone has a certain understanding of this. So today I use a php probe to detect the implementation of the environment. The code is shared with everyone. This article mainly shares examples of how to use php probe environment to detect code. Friends who need it can refer to it
