PHP Limits IP Address range method, PHP limit IP range

This article explains how PHP restricts the range of IP addresses. Share to everyone for your reference. Specific as follows:

Only IP addresses within a limited scope can be accessed

function get_real_ipaddress () {if (!empty ($_server[' http_client_ip ')) {  return $_server[' http_client_ip '];} ElseIf (!empty ($_server[' http_x_forwarded_for ')) {  return $_server[' http_x_forwarded_for '];} return $_server[' Remote_addr '];}  function In_ip_range ($ip, $ip _one, $ip _two = False) {if (! $ip _two) {  return $ip _one = = = $ip;} return Ip2long ($ip _one) *-1 >= ip2long ($IP) *-1 && ip2long ($ip _two) *-1 <= ip2long ($IP) *-1;} function Validate_ip () {$ip = explode (': ', get_real_ipaddress ()); $ip = $ip [0]; if (In_ip_range ($ip, ' 212.76.229.115 ', ' 21 2.76.229.120 ') {  return true;} else if (In_ip_range ($ip, ' 194.78.4.66 ', ' 194.78.4.79 ')) {  return true;} else if ( In_ip_range ($ip, ' 194.8.4.78 ', ' 194.8.4.78 ')) {  return true;} else if (In_ip_range ($ip, ' 0 ', ' 1 ')) {//local  Retu RN true; } header (' location:http://www.bkjia.com ');}
