// 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); } } }

这里有一个函数帮我解决了这个问题:

就像这样叫它

echo arrayToXml("response",$arrayIWantToConvert);
function arrayToXml($thisNodeName,$input){
        if(is_numeric($thisNodeName))
            throw new Exception("cannot parse into xml. remainder :".print_r($input,true));
        if(!(is_array($input) || is_object($input))){
            return "<$thisNodeName>$input</$thisNodeName>";
        }
        else{
            $newNode="<$thisNodeName>";
            foreach($input as $key=>$value){
                if(is_numeric($key))
                    $key=substr($thisNodeName,0,strlen($thisNodeName)-1);
                $newNode.=arrayToXml3($key,$value);
            }
            $newNode.="</$thisNodeName>";
            return $newNode;
        }
    }

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:)

我发现这个解与原来的问题相似

<?php

$test_array = array (
  'bla' => 'blub',
  'foo' => 'bar',
  'another_array' => array (
    'stack' => 'overflow',
  ),
);

class NoSimpleXMLElement extends SimpleXMLElement {
 public function addChild($name,$value) {
  parent::addChild($value,$name);
 }
}
$xml = new NoSimpleXMLElement('<root/>');
array_walk_recursive($test_array, array ($xml, 'addChild'));
print $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();

function toXML($data, $obj = false, $dom) {
    $is_first_level = false;
    if($obj === false) {
        $dom = new DomDocument('1.0');
        $obj = $dom;
        $is_first_level = true;
    }

    if(is_array($data)) {
        foreach($data as $key => $item) {
            $this->toXML($item, $obj->appendChild($dom->createElement($key)), $dom);
        }
    }else {
        $obj->appendChild($dom->createTextNode($data));
    }

    if($is_first_level) {
        $obj->formatOutput = true;
        return $obj->saveXML();
    }
    return $obj;
}
