PHP 利用simplexml_load_file 读取XML对

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <news id="1" year="2015">

总体的思路是利用print_r 进行打印调试，遇到object就用->读取，遇到Array就用［］读取，在调试的时候遇到中文编码的问题用header("Content-Type: text/html; charset=UTF-8");
由于个人水平有限，调试花了一个多小时，希望看到这Blog的人半个小时调试出来。

<?php

$con = mysql_connect("localhost","dbuser","dbpassword");
if (!$con){
  die('Could not connect: ' . mysql_error());
}else{
  echo 'ok';
}
mysql_select_db("dbname", $con);

//必须要转为utf8否则读入数据库报错，注意与UTF-8的区别
mysql_query('set names utf8;');

$xml=simplexml_load_file("zh-cn/news.xml") or die("Error: Cannot create object");

//页面显示
header("Content-Type: text/html; charset=UTF-8");
foreach ($xml as $news) {
   $id = (string)$news['id'];

   $year = (string)$news['year'];

   $title =(string)$news->title;

   $thumbnail = (string)$news->thumbnail;
   $content = (string)$news->content;

//看到这段代码的同学也可以研究一下VALUES中的变量$title,$thumbnail,$content必须要加‘’，如果没有加的话就无法insert   

mysql_query("INSERT INTO news (newsid, year,title,thumbnail,content) VALUES ($id, $year,'$title','$thumbnail','$content')")or die(mysql_error());

   foreach ($news->images->image as $image) {
        $image = (string)$image->source;
        mysql_query("INSERT INTO sub_news (news_id, image) VALUES ($id, '$image')")or die(mysql_error());
   }
}
mysql_close($con);
?>
