There are many ways to obtain IP addresses in php. Next I will introduce how to use linux commands to obtain IP addresses and convert them into array output. Below I also introduce some common php IP address processing instances. PHP obtains the Server IP Address Run ifconfig in PHP to get the Linux Server IP address and output it as an array. The following code is used: The Code is as follows: Copy code Function getServerIp () {// use ifconfig to read the Server IP addre

PHP curl counterfeit IP address and header information code instance, curlheader Although curl is powerful, it can only forge $ _ SERVER ["HTTP_X_FORWARDED_FOR"]. For most IP address detection programs, it is difficult to forge $ _ SERVER ["REMOTE_ADDR: First, the client. php code Copy codeThe Code is as follows:$ Headers ['client-ip'] = '192. 103.229.40 ';$ Headers ['x-FORWARDED-FOR '] = '2017. 103.229.40 ';$ HeaderArr = array ();Foreach ($ headers as $ n => $ v ){$ HeaderArr [] = $ n.

address and target port in the request packet to a process of the rip and port of the back-end RS selected by the scheduling algorithm;Note the following questions:1.RIP and dip must be in the same network segment and should be a private IP address; The gateway to the RS should point to the dip;2. The request message and the response message must be forwarded by the Director, the director is easy to become a system performance bottleneck and trigger a single point of failure;3. Port redirection

IP address and destination port, remain unchanged throughout the message forwarding process4. Switch-------> vs: Send a message with the VIP address to VS, by statically binding the IP address and MAC address on the router.Switch--------> RS: Switch to Rs method, there are two ways: using the Arptables,rs kernel parameters (Arp_announce, Arp_ignore) on the RS5. Port redirection is not supported6. RS for Linux7. The RIP and VIP must be configured on the RS, and the VIP should be configured on th
