php数组转换成xml文件php类
我们经常会用到缓存数据就是把数组保存成xml文档方便处理,下面我们提供一个数组转换成xml文档的类,有需要的朋友可以参考一下.
php数组转换成xml文件php类代码如下:
<?php
$elementLevel = 0;
function array_Xml($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;
}
class ArrayToXML {
/**
* The main function for converting to an XML document.
* Pass in a multi dimensional array and this recrusively loops教程 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 => $value) {
// no numeric keys in our xml please!
if (is_numeric($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 $xml->asXML();
}
}
function arrtoxml($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();
