Copy the code

checkip.php file code:

  3. $userip=$_SERVER['REMOTE_ADDR'];

  4. //Reference the files of the ip library and put all the files in ip.zip in the lib directory
  5. include_once('/lib/ iplimit.class.php');
  6. $iplimit = new iplimit;

  7. if($iplimit->setup($userip))

  8. {
  9. echo 1;
  10. }
  11. else
  12. {
  13. echo 2;
  14. }

Copy code
