PHP中将数组转成XML格式的实现代码

发布时间：2020-05-24 19:07:37 所属栏目：PHP 来源：互联网

导读：网上找的一段代码！然后我自己根据php DOMDocument又写了一段代码，需要的朋友可以参考下。

下面是网上的
<div class="codetitle"><a style="CURSOR: pointer" data="53414" class="copybut" id="copybut53414" onclick="doCopy('code53414')"> 代码如下:<div class="codebody" id="code53414">
class ArrayToXML
{
/
The main function for converting to an XML document.
Pass in a multi dimensional array and this recrusively loops through and builds up an XML document.

@param array $data
@param string $rootNodeName - what you want the root node to be - defaultsto data.
@param SimpleXMLElement $xml - should only be used recursively
@return string XML
/
public static function toXml($data,$rootNodeName = 'data',$xml=null)
{
// turn off compatibility mode as simple xml throws a wobbly if you don't.
if (ini_get('zend.ze1_compatibility_mode') == 1)
{
ini_set ('zend.ze1_compatibility_mode',0);
}
if ($xml == null)
{
$xml = simplexml_load_string("<?xml version='1.0' encoding='utf-8'?><$rootNodeName />");
}
// loop through the data passed in.
foreach($data as $key => $value)
{
// no numeric keys in our xml please!
if (isnumeric($key))
{
// make string key...
$key = "unknownNode". (string) $key;
}
// replace anything not alpha numeric
$key = preg_replace('/[^a-z]/i','',$key);
// if there is another array found recrusively call this function
if (is_array($value))
{
$node = $xml->addChild($key);
// recrusive call.
ArrayToXML::toXml($value,$rootNodeName,$node);
}
else
{
// add single node.
$value = htmlentities($value);
$xml->addChild($key,$value);
}
}
// pass back as string. or simple xml object if you want!
return $xml->asXML();
}
}

下面是我编辑过的代码

<div class="codetitle"><a style="CURSOR: pointer" data="45128" class="copybut" id="copybut45128" onclick="doCopy('code45128')"> 代码如下:<div class="codebody" id="code45128">
function arrtoxml($arr,$dom=0,$item=0){
if (!$dom){
$dom = new DOMDocument("1.0");
}
if(!$item){
$item = $dom->createElement("root");
$dom->appendChild($item);
}
foreach ($arr as $key=>$val){
$itemx = $dom->createElement(is_string($key)?$key:"item");
$item->appendChild($itemx);
if (!is_array($val)){
$text = $dom->createTextNode($val);
$itemx->appendChild($text);
}else {
arrtoxml($val,$dom,$itemx);
}
}
return $dom->saveXML();
}

数组转换成XML格式

<div class="codetitle"><a style="CURSOR: pointer" data="23102" class="copybut" id="copybut23102" onclick="doCopy('code23102')"> 代码如下:<div class="codebody" id="code23102">
<?
$elementLevel = 0 ;
function array_Xml($array,$keys = '')
{
global $elementLevel;
if(!is_array($array))
{
if($keys == ''){
return $array;
}else{
return "n<$keys>" . $array . "</$keys>";
}
}else{
foreach ($array as $key => $value)
{
$haveTag = true;
if (is_numeric($key))
{
$key = $keys;
$haveTag = false;
}
/
The first element
/
if($elementLevel == 0 )
{
$startElement = "<$key>";
$endElement = "</$key>";
}
$text .= $startElement."n";
/*
Other elements
*/
if(!$haveTag)
{
$elementLevel++;
$text .= "<$key>" . array_Xml($value,$key). "</$key>n";
}else{
$elementLevel++;
$text .= array_Xml($value,$key);
}
$text .= $endElement."n";
}
}
return $text;
}
?>

函数描述及例子

<div class="codetitle"><a style="CURSOR: pointer" data="62623" class="copybut" id="copybut62623" onclick="doCopy('code62623')"> 代码如下:<div class="codebody" id="code62623">
<?
$array = array(
"employees" => array(
"employee" => array(
array(
"name" => "name one",
"position" => "position one"
),
array(
"name" => "name two",
"position" => "position two"
),
array(
"name" => "name three",
"position" => "position three"
)
)
)
);
echo array_Xml($array);
?>
