' REMOTE_ADDR ' is the remote IP, the default from the TCP connection is the IP of the client. It is the most accurate, but only gets the direct connection to the server client IP.If the other side through the proxy server online, it is found. Get to the proxy server IP.such as: A->b (proxy)->c, if C through ' remote_addr ', can only get to the IP of B, get less than the IP of a. */$ip =$_se

Python version, the different version of the compiled PYc file is different, 2.5 compiled PYC files, 2.4 version of Python is not executable. Why need PYC file: This demand is very obvious, because the py file can be directly see the source code, if you are developing commercial software, it is impossible to release the source code too? So it needs to be compiled into PYc and then released. Of course, PYC files can also be anti-compilation, different versions of the compiled PYC file is dif
