php取出xml数据库 php获取数据库内容

PHP读取XML数据编码问题,function
characterData改成如下
function
characterData($parser_instance,
$xml_data)
{
global
$name,$position;
$xml_data=https://www.04ip.com/post/iconv("utf-8","gb2312",$xml_data);//转换成gb2312
if($position)
echo
$xml_data."br";
if($name)
echo
$xml_data."br";
}
显示的那个页面也要有charset=gb2312
PHP 获取XML数据给个小例子:
1.直接是xml字符串
?php
$string = XML
?xml version='1.0'?
document
titleForty What?/title
fromJoe/from
toJane/to
body
I know that's the answer -- but what's the question?
/body
/document
XML;
$xml = simplexml_load_string($string);
print_r($xml);
?
2. xml文件的
?php
if (file_exists('test.xml')) {
$xml = simplexml_load_file('test.xml');
print_r($xml);
} else {
exit('Failed to open test.xml.');
}
?
如何通过PHP生成和获取XML格式数据1自己拼,XML编码
?php
header('Content-type:text/xml');
echo "?xml version='1.0' encoding='utf-8'";
echo "book";
echo "PHP";
echo "namePHP程序开发范例宝典/name";
echo "price 单位='元/本'89.00/price";
echo "date2007-09-01/date";
echo "/PHP";
echo "/book";
?
拼接的效果
2从数据库中查询再拼XML编码
?php
$dsn="mysql:host=localhost;dbname=test";
try {
$pdo = new PDO($dsn,'root','passwowd'); //初始化一个PDO对象,就是创建了数据库连接对象$pdo
$query="select * from book";//定义SQL语句
$pdo-query('set names utf8');
$result=$pdo-prepare($query); //准备查询语句
$result-execute();//执行查询语句 , 并返回结果集
$arr='';
while($res=$result-fetch()){
$arr.='PHPid'.$res[0].'/idname'.$res[1].'/namedate'.$res[2].'/date'.'price'.$res[3].'/price/PHP';
}
echo "?xml version='1.0' encoding='utf-8'?book".$arr.'/book';
} catch (PDOException $e) {
die ("Error!: ".$e-getMessage()."br");
}
?
拼接的效果
3使用ajax获取,DOM解析
!DOCTYPE html
html lang="en"
head
meta charset="UTF-8"
titlexml/title
/head
body
script
function check(){
var xhr=new XMLHttpRequest();
xhr.open('GET','xml.php');
xhr.onreadystatechange=function(){
if(xhr.readyState==4xhr.status==200){
console.log(xhr.responseText);
//初始化 DOM解析对象
var domParser = new DOMParser();
//字符串解码为对象
var xmlDoc = domParser.parseFromString(xhr.responseText,'text/xml');
//按标签名获取元素 返回数组
var elements = xmlDoc.getElementsByTagName('PHP');
//拼接html格式字符串
var str ='trthid/ththname/ththdate/ththprice/th/tr';
for (var i=0;ielements.length;i++){
var id=elements[i].getElementsByTagName('id')[0].firstChild.nodeValue;
var name=elements[i].getElementsByTagName('name')[0].firstChild.nodeValue;
var date=elements[i].getElementsByTagName('date')[0].firstChild.nodeValue;
【php取出xml数据库 php获取数据库内容】var price=elements[i].getElementsByTagName('price')[0].firstChild.nodeValue;
str+= 'trtd'+id+'/tdtd'+name+'/tdtd'+date+'/tdtd'+price+'/td/tr';
}
document.getElementById('table2').innerHTML=str;
}
};
xhr.send(null);
}
/script
button onclick="check();"点我/button
table id="table2" border="2" cellspacing="0"
/table
/body
/html

补充:
使用JSON
1数据库查询 , 自己拼 JSON 编码
?php
$dsn="mysql:host=localhost;dbname=test";
try {
