// Structered array for XML convertion. $data_array = array( array( '#xml_tag' => 'a', '#xml_value' => '', '#tag_attributes' => array( array( 'name' => 'a_attr_name', 'value' => 'a_attr_value', ), ), '#subnode' => array( array( '#xml_tag' => 'aa', '#xml_value' => 'aa_value', '#tag_attributes' => array( array( 'name' => 'aa_attr_name', 'value' => 'aa_attr_value', ), ), '#subnode' => FALSE, ), ), ), array( '#xml_tag' => 'b', '#xml_value' => 'b_value', '#tag_attributes' => FALSE, '#subnode' => FALSE, ), array( '#xml_tag' => 'c', '#xml_value' => 'c_value', '#tag_attributes' => array( array( 'name' => 'c_attr_name', 'value' => 'c_attr_value', ), array( 'name' => 'c_attr_name_1', 'value' => 'c_attr_value_1', ), ), '#subnode' => array( array( '#xml_tag' => 'ca', '#xml_value' => 'ca_value', '#tag_attributes' => FALSE, '#subnode' => array( array( '#xml_tag' => 'caa', '#xml_value' => 'caa_value', '#tag_attributes' => array( array( 'name' => 'caa_attr_name', 'value' => 'caa_attr_value', ), ), '#subnode' => FALSE, ), ), ), ), ), ); // creating object of SimpleXMLElement $xml_object = new SimpleXMLElement('<?xml version=\"1.0\"?><student_info></student_info>'); // function call to convert array to xml array_to_xml($data_array, $xml_object); // saving generated xml file $xml_object->asXML('/tmp/test.xml'); /** * Converts an structured PHP array to XML. * * @param Array $data_array * The array data for converting into XML. * @param Object $xml_object * The SimpleXMLElement Object * * @see https://gist.github.com/drupalista-br/9230016 * */ function array_to_xml($data_array, &$xml_object) { foreach($data_array as $node) { $subnode = $xml_object->addChild($node['#xml_tag'], $node['#xml_value']); if ($node['#tag_attributes']) { foreach ($node['#tag_attributes'] as $tag_attributes) { $subnode->addAttribute($tag_attributes['name'], $tag_attributes['value']); } } if ($node['#subnode']) { array_to_xml($node['#subnode'], $subnode); } } }

我使用了几个函数，我写了一段时间来生成xml来回传递从PHP和jQuery等… 既不使用任何额外的框架，只是单纯地生成一个字符串，然后可以使用SimpleXML(或其他框架)…

如果它对任何人有用，请使用它:)

function generateXML($tag_in,$value_in="",$attribute_in=""){
    $return = "";
    $attributes_out = "";
    if (is_array($attribute_in)){
        if (count($attribute_in) != 0){
            foreach($attribute_in as $k=>$v):
                $attributes_out .= " ".$k."=\"".$v."\"";
            endforeach;
        }
    }
    return "<".$tag_in."".$attributes_out.((trim($value_in) == "") ? "/>" : ">".$value_in."</".$tag_in.">" );
}

function arrayToXML($array_in){
    $return = "";
    $attributes = array();
    foreach($array_in as $k=>$v):
        if ($k[0] == "@"){
            // attribute...
            $attributes[str_replace("@","",$k)] = $v;
        } else {
            if (is_array($v)){
                $return .= generateXML($k,arrayToXML($v),$attributes);
                $attributes = array();
            } else if (is_bool($v)) {
                $return .= generateXML($k,(($v==true)? "true" : "false"),$attributes);
                $attributes = array();
            } else {
                $return .= generateXML($k,$v,$attributes);
                $attributes = array();
            }
        }
    endforeach;
    return $return;
}   

爱所有人:)

function array2xml($array, $xml = false){

    if($xml === false){

        $xml = new SimpleXMLElement('<?xml version=\'1.0\' encoding=\'utf-8\'?><'.key($array).'/>');
        $array = $array[key($array)];

    }
    foreach($array as $key => $value){
        if(is_array($value)){
            $this->array2xml($value, $xml->addChild($key));
        }else{
            $xml->addChild($key, $value);
        }
    }
    return $xml->asXML();
}

您可以使用我一直在研究的XMLParser。

$xml = XMLParser::encode(array(
    'bla' => 'blub',
    'foo' => 'bar',
    'another_array' => array (
        'stack' => 'overflow',
    )
));
// @$xml instanceof SimpleXMLElement
echo $xml->asXML();

会导致:

<?xml version="1.0"?>
<root>
    <bla>blub</bla>
    <foo>bar</foo>
    <another_array>
        <stack>overflow</stack>
    </another_array>
</root>

整个XML结构定义在$data数组中:

function array2Xml($data, $xml = null)
{
    if (is_null($xml)) {
        $xml = simplexml_load_string('<' . key($data) . '/>');
        $data = current($data);
        $return = true;
    }
    if (is_array($data)) {
        foreach ($data as $name => $value) {
            array2Xml($value, is_numeric($name) ? $xml : $xml->addChild($name));
        }
    } else {
        $xml->{0} = $data;
    }
    if (!empty($return)) {
        return $xml->asXML();
    }
}

我发现所有的答案都是使用过多的代码。这里有一个简单的方法:

function to_xml(SimpleXMLElement $object, array $data)
{   
    foreach ($data as $key => $value) {
        if (is_array($value)) {
            $new_object = $object->addChild($key);
            to_xml($new_object, $value);
        } else {
            // if the key is an integer, it needs text with it to actually work.
            if ($key != 0 && $key == (int) $key) {
                $key = "key_$key";
            }

            $object->addChild($key, $value);
        }   
    }   
}   

然后，将数组发送到使用递归的函数中就很简单了，因此它将处理多维数组:

$xml = new SimpleXMLElement('<rootTag/>');
to_xml($xml, $my_array);

现在$xml包含了一个漂亮的xml对象，它完全基于您编写数组的方式。

print $xml->asXML();
