In our previous article, we have introduced to you what a php probe is and what its main function is. If you are exposed to cms, you may have some understanding. Of course, it doesn’t matter. After reading this article, you will know about php probe. What does the needle do?
php probes are usually used to detect space, server running status and php related information. They can check server hard disk resources, memory usage, network card traffic, system load, server time, and the time you use in real time. PHP version, mysql database version and other information.
A simple understanding is to look at the running status of your program, which directories are writable, and what versions of php and mysql are. If you want to know the running status of your own php, or write one yourself cms, you can put this php probe inside.

In fact, you still need to run it yourself. It is very simple. Take a look at the source code program first:
