一般我們直接使用dom來處理xml文檔時如果裡面有中文就會把中文轉換成亂碼了，下面我們通過使用iconv()函數實現編碼轉換，防止中文亂碼.
代碼如下
復制代碼
<?php
//讀取xml文件
$xmlDoc = new DOMDocument();
$xmlDoc->load('http://127.0.0.1/holiday.xml');
//獲得該xml文件中的所有年份
$years = $xmlDoc->getElementsByTagName("year");
//對每一個年份進行處理
foreach($years as $year){
//獲得具體的年份值
$yearNames = $year->getElementsByTagName("yearName");
$yearName = $yearNames->item(0)->nodeValue;
echo $yearName.'年'.'</br>';
//獲得該年份下所有的假日
$holidays = $year->getElementsByTagName("holiday");
//對每一個假日進行處理
foreach($holidays as $holiday){
//獲得假日名稱
$holidayNames = $holiday->getElementsByTagName("holidayName");
$holidayName = $holidayNames->item(0)->nodeValue;
echo iconv('utf-8','gb2312', $holidayName).': '.'</br>';
//獲得假日的具體放假日期
$daysOffs = $holiday->getElementsByTagName("daysOff");
$daysOff = $daysOffs->item(0);
$froms = $daysOff->getElementsByTagName("from");
$from = $froms->item(0)->nodeValue;
$tos = $daysOff->getElementsByTagName("to");
$to = $tos->item(0)->nodeValue;
echo '假期為：'.$from.' 至 '.$to.'</br>';
//獲得針對該假日的調休日期
$overTimes = $holiday->getElementsByTagName("overTime");
$overTime = $overTimes->item(0);
$days = $overTime->getElementsByTagName("day");
//通過判斷，有調休日期則顯示，沒有則不顯示
if($days->length!=0){
echo '調休日為：';
foreach($days as $day){
echo $day->nodeValue.' ';
}
echo '</br>';
}
echo '</br>';
}
}
?>

設計知識點：
1、XML節點循環讀取
2、用iconv()函數實現編碼轉換，防止中文亂碼
