禁止单个ip

禁止ip段
复制代码 代码如下:
<?php
//加ip访问限制
if(getenv('http_client_ip') && strcasecmp(getenv('http_client_ip'), 'unknown')) {
$userip = getenv('http_client_ip');
} elseif(getenv('http_x_forwarded_for') && strcasecmp(getenv('http_x_forwarded_for'), 'unknown')) {
$userip = getenv('http_x_forwarded_for');
} elseif(getenv('remote_addr') && strcasecmp(getenv('remote_addr'), 'unknown')) {
$userip = getenv('remote_addr');
} elseif(isset($_server['remote_addr']) && $_server['remote_addr'] && strcasecmp($_server['remote_addr'], 'unknown')) {
$userip = $_server['remote_addr'];
}
$ban_range_low=ip2long("217.0.0.0"); //ip段上
$ban_range_up=ip2long("217.255.255.255");//ip段尾
$ip=ip2long($userip]);
if ($ip>$ban_range_low && $ip<$ban_range_up)
{
print "banned";
exit();
}
?>
