Php does not support cookiecookie, so session is also not supported. How can we track users like this !, It seems that there is no way. you can't catch the Mac address of your phone. It seems that I have never heard of the phone's support for cookies. it seems that there is no way to discuss it. I can't catch the Mac address of the phone. I have never heard of phone support for cookies. you can also create SSI php by yourself.
