禁止单个ip

禁止单个ip
<?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'];
}
$banned_ip = array (
"127.0.0.1",
"203.0.0.1",
"56.12.50.65",
"192.168.1.88"
);
if (in_array($userip,$banned_ip))
{
die ("your ip is block to connect !");
}
echo "测试";
?>
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(); 
} 
?>
