我了解下下面的代码是干嘛用的，有什么意思！

Question

php代码：<?php class Index {  private $index = array("192.168.100.1","74.125.19.106");  function xml($resolve)  {  foreach ($this->index as $val) {  print $val;  if($resolve)  {  print "(".gethostbyaddr($val).")";  }  print "\n";  }  } } $xml = simplexml_load_file("settings.xml"); $ml = new Index(); $ml->xml( (string)$xml->resolvedomains);XML代码：<?xml version="1.0" encoding="UTF-8"?><note><settings><resolvedomains>false</resolvedomains></settings></note>   

Answer 1

是根据xml动态配置主机属性，是加载下面xml代码，根据resolvedomains字段的值做出不同的操作。
