下面是网上的 复制代码 代码如下: 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 => $value) { // no numeric keys in our xml please! if (is_numeric($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 $xml->asXML(); } }
下面是我编辑过的代码 复制代码 代码如下: function arrtoxml($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(); }
