Question

我使用nmap扫描网络中的可用IP，我想只使用PHP扫描IP地址，只保存数组中的IP地址。

这里是文本文件输出。

Starting Nmap 6.40 ( http://nmap.org ) at 2013-10-15 22:07 SE Asia Standard Time
Nmap scan report for 110.77.144.25
Host is up (0.042s latency).
Nmap scan report for 110.77.144.27
Host is up (0.051s latency).
Nmap scan report for 110.77.144.88
Host is up (0.033s latency).
Nmap scan report for 110.77.144.90
Host is up (0.037s latency).
Nmap scan report for 110.77.144.91
Host is up (0.038s latency).
Nmap scan report for 110.77.144.92
Host is up (0.034s latency).
Nmap scan report for 110.77.144.93
Host is up (0.035s latency).
Nmap scan report for 110.77.144.137
Host is up (0.063s latency).
Nmap scan report for 110.77.144.139
Host is up (0.037s latency).
Nmap scan report for 110.77.144.145
Host is up (0.064s latency).
Nmap scan report for 110.77.144.161
Host is up (0.074s latency).
Nmap done: 256 IP addresses (42 hosts up) scanned in 14.44 seconds

我希望像这样输出保存在数组中

$available = array("110.77.233.1", "110.77.233.2", 
                   "110.77.233.3", "110.77.233.4",
                   "110.77.254.16");

我该如何处理PHP？

Answer 1

您可以执行以下操作：

$lines = file('file.txt');    
for ($i=1; $i <= count($lines); $i+=2) { 
    list($IP) = array_reverse(explode(' ', $lines[$i]));
    $available[] = $IP;
}
array_pop($available);
print_r($available);

Demo!

Answer 2

-oX的结构化输出简化了生活：

$ nmap -sP -oX output.xml  10.60.12.50-59

Starting Nmap 6.00 ( http://nmap.org ) at 2013-10-15 20:09 CEST
Nmap scan report for 10.60.12.50-59
Host is up (0.000080s latency).
Nmap done: 10 IP addresses (1 host up) scanned in 1.41 seconds

$ php -r'$d = simplexml_load_file("output.xml");
> var_dump(array_map("strval",$d->xpath("//host[status[@state=\"up\"]]/address/@addr")));'
array(1) {
  [0] =>
  string(11) "10.60.12.59"
}

Answer 3

试试这个：

nmap -v -sn 110.77.144.25-255 | grep ^Nmap | awk '{print $5;}' | grep ^[0-9].*

结果将是：

110.77.144.25
110.77.144.26
...
110.77.144.254
110.77.144.255

保存输出到文件并从PHP读取：

COMMAND:

nmap -v -sn 110.77.144.25-255 | grep ^Nmap | awk '{print $5;}' | grep ^[0-9].* > output.txt

PHP:

<?php
$fp = fopen('[path to file]/output.txt', 'r');
while(!feof($fp)) {
    $each_ip = fgets($fp, 4096);
    echo $each_ip;
}
fclose($fp);

仅搜索日志文件中的IP并保存在数组中
