php禁止某ip或ip地址段访问的方法_php技巧
本文实例讲述了php禁止某ip或ip地址段访问的方法,分享给大家供大家参考。具体分析如下:
因为还没有深入学习Apache和nginx 所以用PHP写了一个可以禁用地址的小程序
使用时只需:
<?php include("banIP.php");?>
即可
禁用单个ip如下:
<?php //禁用ip地址 $ip=$_SERVER["REMOTE_ADDR"]; $ban=file_get_contents("ban.dat"); if(stripos($ban,$ip)) { die("Your IP Address is:$ip,you're forbiden to view this page!"); } echo "Your IP Address is:$ip,hello!"; ?>
ban.dat文件如下:
BEGIN: 119.184.251.245 127.0.0.1 192.168.1.100
禁用ip段如下:
<?php //禁用ip地址 $ip=$_SERVER["REMOTE_ADDR"]; while($ip[count($ip-1)]!='.')$ip=substr($ip,1, -1); //整理出ip段 $ban=file_get_contents("ban.dat"); if(stripos($ban,$ip)) { die("U're forbiden to view this page!"); } echo "Hello!"; ?>
希望本文所述对大家的php程序设计有所帮助。
