PHP中将数组转成XML格式的实现代码

下面是网上的
代码如下:

1. class ArrayToXML
   
2. {
   
3. /**
   
4. * The main function for converting to an XML document.
   
5. * Pass in a multi dimensional array and this recrusively loops through and builds up an XML document.
   
6. *
   
7. * @param array $data
   
8. * @param string $rootNodeName - what you want the root node to be - defaultsto data.
   
9. * @param SimpleXMLElement $xml - should only be used recursively
   
10. * @return string XML
    
11. */
    
12. public static function toXml($data, $rootNodeName = 'data', $xml=null)
    
13. {
    
14. // turn off compatibility mode as simple xml throws a wobbly if you don't.
    
15. if (ini_get('zend.ze1_compatibility_mode') == 1)
    
16. {
    
17. ini_set ('zend.ze1_compatibility_mode', 0);
    
18. }
    
19. if ($xml == null)
    
20. {
    
21. $xml = simplexml_load_string("<?xml version='1.0' encoding='utf-8'?><$rootNodeName />");
    
22. }
    
23. // loop through the data passed in.
    
24. foreach($data as $key => $value)
    
25. {
    
26. // no numeric keys in our xml please!
    
27. if (is_numeric($key))
    
28. {
    
29. // make string key...
    
30. $key = "unknownNode_". (string) $key;
    
31. }
    
32. // replace anything not alpha numeric
    
33. $key = preg_replace('/[^a-z]/i', '', $key);
    
34. // if there is another array found recrusively call this function
    
35. if (is_array($value))
    
36. {
    
37. $node = $xml->addChild($key);
    
38. // recrusive call.
    
39. ArrayToXML::toXml($value, $rootNodeName, $node);
    
40. }
    
41. else
    
42. {
    
43. // add single node.
    
44. $value = htmlentities($value);
    
45. $xml->addChild($key,$value);
    
46. }
    
47. }
    
48. // pass back as string. or simple xml object if you want!
    
49. return $xml->asXML();
    
50. }
    
51. }

下面是我编辑过的代码
代码如下:

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

数组转换成XML格式
代码如下:

1. <?
   
2. $elementLevel = 0 ;
   
3. function array_Xml($array, $keys = '')
   
4. {
   
5. global $elementLevel;
   
6. if(!is_array($array))
   
7. {
   
8. if($keys == ''){
   
9. return $array;
   
10. }else{
    
11. return "\n<$keys>" . $array . "</$keys>";
    
12. }
    
13. }else{
    
14. foreach ($array as $key => $value)
    
15. {
    
16. $haveTag = true;
    
17. if (is_numeric($key))
    
18. {
    
19. $key = $keys;
    
20. $haveTag = false;
    
21. }
    
22. /**
    
23. * The first element
    
24. */
    
25. if($elementLevel == 0 )
    
26. {
    
27. $startElement = "<$key>";
    
28. $endElement = "</$key>";
    
29. }
    
30. $text .= $startElement."\n";
    
31. /**
    
32. * Other elements
    
33. */
    
34. if(!$haveTag)
    
35. {
    
36. $elementLevel++;
    
37. $text .= "<$key>" . array_Xml($value, $key). "</$key>\n";
    
38. }else{
    
39. $elementLevel++;
    
40. $text .= array_Xml($value, $key);
    
41. }
    
42. $text .= $endElement."\n";
    
43. }
    
44. }
    
45. return $text;
    
46. }
    
47. ?>

函数描述及例子
代码如下:

1. <?
   
2. $array = array(
   
3. "employees" => array(
   
4. "employee" => array(
   
5. array(
   
6. "name" => "name one",
   
7. "position" => "position one"
   
8. ),
   
9. array(
   
10. "name" => "name two",
    
11. "position" => "position two"
    
12. ),
    
13. array(
    
14. "name" => "name three",
    
15. "position" => "position three"
    
16. )
    
17. )
    
18. )
    
19. );
    
20. echo array_Xml($array);
    
21. ?>
