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==4 xhr.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;

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 {

$pdo = new PDO($dsn,'root','password'); //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

$a=$arr='';

while($res=$result-fetch()){

$arr.='{"id":'.'"'.$res[0].'",'.'"name":'.'"'.$res[1].'",'.'"time":'.'"'.$res[2].'",'.'"jia":'.'"'.$res[3].'",'.'"zhe":'.'"'.$res[4].'",'.'"chu":'.'"'.$res[5].'"},';

}

echo $a="[".substr($arr,0,strlen($arr)-1)."]";

} catch (PDOException $e) {

die ("Error!: ".$e-getMessage()."br");

}

?

2数据库查询,函数 JSON 编码

?php

$dsn="mysql:host=localhost;dbname=test";

try {

$pdo = new PDO($dsn,'root','password'); //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

$res=$result-fetchAll();

//JSON 编码

echo json_encode($res);

} catch (PDOException $e) {

die ("Error!: ".$e-getMessage()."br/");

}

?

效果

3ajax获取,JSON解析

!DOCTYPE html

html lang="en"

head

meta charset="UTF-8"

titleJSON/title

/head

body

script

function check() {

var XHR = new XMLHttpRequest();

XHR.open('GET','JSON.php');

XHR.onreadystatechange = function (){

if(XHR.readyState == 4 XHR.status ==200){

var books =JSON .parse(XHR.responseText);

var books2='trthid/ththbookname/ththtime/ththprice/ththmarker/ththpublisher/th/tr'

for (var i=0;ibooks.length;i++){

books2+= 'trtd'+(books[i ].id)+'/tdtd'+(books[i ].name)+'/tdtd'+(books[i ].time)+'/tdtd'+(books[i ].jia)+'/tdtd'+(books[i ].zhe)+'/tdtd'+(books[i ].chu)+'/td/tr';

}

document.getElementById('table2').innerHTML=books2;

}

};

XHR.send(null);

}

/script

input type="button" value="点我" onclick="check();"

table id="table2" border="2" cellspacing="0"/table

/body

/html

PHP如何取XML中数据

转成数组

?php/*** function:使用字符串方式读XML文件* author:JetWu* date:2016.12.03**/$file = './write_str.xml';$con = file_get_contents($file); //XML标签配置$xmlTag = array( 'starttime', 'endtime', 'school'); $arr = array();foreach($xmlTag as $x) { preg_match_all("/".$x.".*\/".$x."/", $con, $temp); $arr[] = $temp[0];}//去除XML标签并组装数据$data = array();foreach($arr as $key = $value) { foreach($value as $k = $v) { $a = explode($xmlTag[$key].'', $v); $v = substr($a[1], 0, strlen($a[1])-2); $data[$k][$xmlTag[$key]] = $v; }}echo 'pre';print_r($data);

PHP怎么解析微信支付结果返回的xml

php解析xml报文的方法是DOMDocument:

解析方法如下:

$xmlstring = XML

?xml version='1.0'?

document

cmd attr='default'login/cmd

loginimdonkey/login

/document

XML;

$dom = new DOMDocument();

$dom-loadXML($xmlstring);

print_r(getArray($dom-documentElement));

function getArray($node) {

$array = false;

if ($node-hasAttributes()) {

foreach ($node-attributes as $attr) {

$array[$attr-nodeName] = $attr-nodeValue;

}

}

if ($node-hasChildNodes()) {

if ($node-childNodes-length == 1) {

$array[$node-firstChild-nodeName] = getArray($node-firstChild);

} else {

foreach ($node-childNodes as $childNode) {

if ($childNode-nodeType != XML_TEXT_NODE) {

$array[$childNode-nodeName][] = getArray($childNode);

}

}

}

} else {

return $node-nodeValue;

}

return $array;

}
