php:如何将数组转换为支持属性的XML(domi?)

查看源代码,显然您传递了第二个参数 "attributes" 到 attachToXml :

public function attachToXml($data, $prefix, &$parentNode = false) {
    if(!$parentNode) {
        $parentNode = &$this->mainNode;
    }
    // i don't like how this is done, but i can't see an easy alternative
    // that is clean. if the prefix is attributes, instead of creating
    // a node, just put all of the data onto the parent node as attributes
    if(strtolower($prefix) == 'attributes') {
        // set all of the attributes onto the node
        foreach($data as $key=>$val)
            $parentNode->setAttribute($key, $val);

        $node = &$parentNode;
    }
    //...
}
