php操作xml并将其插入数据库的实现方法

<?php
header('content-type:text/html;charset=utf-8');
mysql_connect('localhost', 'root', '');
mysql_select_db('test');
mysql_query('SET names utf8');
$xml_array=simplexml_load_file('suggest.xml'); //将XML中的数据,读取到数组对象中

foreach($xml_array as $tmp){
	$sql = "insert into `countries` (`id` ,`value`) VALUES (NULL , '".$tmp->field."')";
	mysql_query($sql);
echo $tmp->field."<br>";
}
?>
