This article mainly introduces about PHP using Curl to forge source IP and refer method, has a certain reference value, now share to everyone, the need for friends can refer to

This example describes how PHP uses Curl to forge source IPs and refer. Share to everyone for your reference, as follows:

PHP Curl spoofed source IP and route Refer instance code 1:

Random ipfunction rand_ip () {$ip 2id= round (rand (600000, 2550000)/10000);//First method, direct generation $IP 3id= round (rand (600000, 2550000) /10000); $ip 4id= Round (rand (600000, 2550000)/10000); Here is the second method, randomly extracting $arr _1 = Array ("218", "218", "66", "66", "218", "218", "60", "60", "202", "204", "66", "66", "66", "59" in the following data, "61", "60", "222", "221", "66", "59", "60", "60", "66", "218", "218", "62", "63", "64", "66", "66", "122", "211"); $randarr = Mt_rand (0,count ($arr _1)-1); $ip 1id = $arr _1[$randarr]; return $ip 1id.
