php数组转成xml的代码

2. class ArrayToXML
3. {
4. /**
5. * The main function for converting to an XML document.
6. * Pass in a multi dimensional array and this recrusively loops through and builds up an XML document.
7. *
8. * @param array $data
9. * @param string $rootNodeName - what you want the root node to be - defaultsto data.
10. * @param SimpleXMLElement $xml - should only be used recursively
11. * @return string XML

13. public static function toXml($data, $rootNodeName = 'data', $xml=null)
14. {
15. // turn off compatibility mode as simple xml throws a wobbly if you don't.
16. if (ini_get('zend.ze1_compatibility_mode') == 1)
17. {
18. ini_set ('zend.ze1_compatibility_mode', 0);

21. if ($xml == null)

2、自己写的php数组转xml的代码

2. function arrtoxml($arr,$dom=0,$item=0){
3. if (!$dom){
4. $dom = new DOMDocument("1.0");
5. }
6. if(!$item){
7. $item = $dom->createElement("root");
8. $dom->appendChild($item);
9. }
10. foreach ($arr as $key=>$val){
11. $itemx = $dom->createElement(is_string($key)?$key:"item");
12. $item->appendChild($itemx);
13. if (!is_array($val)){
14. $text = $dom->createTextNode($val);
15. $itemx->appendChild($text);
17. }else {
18. arrtoxml($val,$dom,$itemx);
19. }
20. }
21. return $dom->saveXML();
22. }
23. ?>
