将PHP数组转成XML
这是一个封装好的PHP类,用来将数组数据转成XML数据
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) { $xml = simplexml_load_string(""); } // loop through the data passed in. foreach($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(); } }
