Write it again to deepen your memory. Today I compiled this relatively simple PHP domain name WHOIS query tool. The source code is relatively simple. I released it so that friends who also learn scripts can study it together. We can also upload the tool to our own website as part of the tool set. How to use it is simple: 1.
