<?php include("banIP.php");?>

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!";
?>
