PHP 返回 gethostbyname($lookup) 值

发布于 2024-11-16 10:16:32 字数 686 浏览 0 评论 0原文

我使用下面的代码（简化版本）来确定我的 IP 是否在黑名单中。我需要修改它才能确定 IP 是否在白名单上。该函数将要求我查看返回的特定代码。

127.0.0.1 
127.0.0.2 
127.0.0.3 
127.0.0.4 
127.0.0.5

如何调整以在脚本运行时返回（代码）输出值？

$host = '222.22.222.222';
$rbl  = 'hostkarma.junkemailfilter.com';
$rev = array_reverse(explode('.', $host));
$lookup = implode('.', $rev) . '.' . $rbl;
if ($lookup != gethostbyname($lookup)) {

   echo "ip: $host is listed in $rbl\n";
} else {
   echo "ip: $host NOT listed in $rbl\n";
}

编辑：抱歉，如果 IP 地址位于 $rlb 中输入的黑名单中，则上述脚本的功能将返回确认。但是，Hostkarma 返回一个代码，上面显示的 127.0 代码之一，因为每个代码表示不同的块状态。我需要获取代码。 “回显$lookup；”仅返回反向查找，如下所示：222.222.22.222.hostkarma.junkemailfilter.com

I am using the code below (simplified version) to determine if my IPs are on a blacklist. I need to modify it to be able to determine if an IP is on a Whitelist. The function will require me to see a specific code returned.

127.0.0.1 
127.0.0.2 
127.0.0.3 
127.0.0.4 
127.0.0.5

How can this be adjusted to return the (code) output value when the script runs?

$host = '222.22.222.222';
$rbl  = 'hostkarma.junkemailfilter.com';
$rev = array_reverse(explode('.', $host));
$lookup = implode('.', $rev) . '.' . $rbl;
if ($lookup != gethostbyname($lookup)) {

   echo "ip: $host is listed in $rbl\n";
} else {
   echo "ip: $host NOT listed in $rbl\n";
}

EDIT: Sorry guys, The function of the script above will return confirmation if the IP address is on the blacklist entered in $rlb. However, Hostkarma returns a code, one of the 127.0 codes shown above as each code indicates a different block status. I need to get the code. "echo $lookup;" just returns the reverse lookup, like this: 222.222.22.222.hostkarma.junkemailfilter.com

$lookup = implode('.', $rev) . '.' . $rbl;
$value = gethostbyname($lookup);
if ($lookup != $value){
   echo "ip: $host is listed in $rbl\n";
   echo "return value: $value\n";
}
else{
   echo "ip: $host NOT listed in $rbl\n";
}

127.xxx 代码应作为 gethostbyname 返回的值提供给您。

$lookup = implode('.', $rev) . '.' . $rbl;
$value = gethostbyname($lookup);
if ($lookup != $value){
   echo "ip: $host is listed in $rbl\n";
   echo "return value: $value\n";
}
else{
   echo "ip: $host NOT listed in $rbl\n";
}

The 127.x.x.x code should be given to you as the value returned by gethostbyname.
