有时需要生成随机的国内IP,比如采集等场合。那这个函数会帮上你。
/** * 随机生成国内的IP地址头 * @return [type] [description] */ function rand_ip() { $ip_long = array( array('607649792', '608174079'), //36.56.0.0-36.63.255.255 array('1038614528', '1039007743'), //61.232.0.0-61.237.255.255 array('1783627776', '1784676351'), //106.80.0.0-106.95.255.255 array('2035023872', '2035154943'), //121.76.0.0-121.77.255.255 array('2078801920', '2079064063'), //123.232.0.0-123.235.255.255 array('-1950089216', '-1948778497'), //139.196.0.0-139.215.255.255 array('-1425539072', '-1425014785'), //171.8.0.0-171.15.255.255 array('-1236271104', '-1235419137'), //182.80.0.0-182.92.255.255 array('-770113536', '-768606209'), //210.25.0.0-210.47.255.255 array('-569376768', '-564133889'), //222.16.0.0-222.95.255.255 ); $rand_key = mt_rand(0, 9); $ip = long2ip(mt_rand($ip_long[$rand_key][0], $ip_long[$rand_key][1])); $headers['CLIENT-IP'] = $ip; $headers['X-FORWARDED-FOR'] = $ip; $headerArr = array(); foreach ($headers as $n => $v) { $headerArr[$n] =$v; } return $headerArr; }
调用:
print_r (rand_ip());
结果,每次刷新IP都会不同:
Array ( [CLIENT-IP] => 222.75.155.43 [X-FORWARDED-FOR] => 222.75.155.43 )
