代码如下：
<?php
header("content-type:text/html;charset=utf-8");
$con = mysql_connect('localhost','root','root');
mysql_query('set names utf8');
$db = mysql_select_db('wh'); // var_dump($con,$db);
$sql = "select * from stu";
$res = mysql_query($sql)or die(mysql_error()); while($row=mysql_fetch_assoc($res)){
$arr[] = array(
'name' => $row['name'],
'age' => $row['age'],
'email' => $row['email'] );
} $doc = new DOMDocument('1.0', 'utf-8'); // 声明版本和编码 // var_dump($doc);
$doc->formatOutput = true; $r = $doc->createElement("root");
$doc->appendChild($r); foreach ($arr as $dat) {
$b = $doc->createElement("data"); $name = $doc->createElement("name");
$name->appendChild($doc->createTextNode($dat['name']));
$b->appendChild($name); $sex = $doc->createElement("age");
$sex->appendChild($doc->createTextNode($dat['age']));
$b->appendChild($sex); $age = $doc->createElement("email");
$age->appendChild($doc->createTextNode($dat['email']));
$b->appendChild($age); $r->appendChild($b);
} echo $doc->saveXML(); ?>
2.读取xml文件信息
a.准备xml文件: f.xml。如：
<?xml version="1.0" encoding="utf-8"?>
<root>
<data>
<name>wuheng</name>
<age>23</age>
<email>demo@qq.com</email>
</data>
<data>
<name>wuheng009</name>
<age>22</age>
<email>dem6@qq.com</email>
</data>
<data>
<name>wuheng555</name>
<age>22</age>
<email>dem6@qq.com</email>
</data>
<data>
<name>xia</name>
<age>11</age>
<email>456@qq.com</email>
</data>
<data>
<name>xia11</name>
<age>12</age>
<email>466@qq.com</email>
</data>
</root>
b.具体的代码，如下：
<?php
header("content-type:text/html;charset=utf-8");
$url = "f.xml";
$reader = new XMLReader(); //实例化XMLReader
$reader->open($url); //获取xml
$i=1;
while ($reader->read()) {
if ($reader->nodeType == XMLReader::TEXT) { //判断node类型
$m = $i%3;
if($m==1)
$name = $reader->value; //读取node值
if($m==2)
$age = $reader->value;
if($m==0){
$email = $reader->value;
$arr[] = array(
'name' => $name,
'age' => $age,
'email' => $email
);
}
$i++;
}
}
print_r($arr); ?>
