depends on your network environment. In general, if your server uses a real IP address (the address is usually allocated to you by the IDC), the firewall's transparent mode will be selected. In this mode, your server looks like you are directly facing the internet, and all access requests to the server are directly sent to the server. Of course, packets will pass the firewall detection before they arrive at the server, and packets that do not comply with the rules will be discarded (from the pe

Rule 1: Never trust external data or input
The first thing you must realize about WEB application security is that you should not trust external data. External data (outside) includes any data that is not directly entered by the programmer in the PHP code.
