如何将数组转换为PHP中的SimpleXML对象?
当前回答
使用FluidXML，您可以从一个PHP数组开始，生成一个用于SimpleXML的XML…只有两行代码。
$fluidxml = fluidxml($array);
$simplexml = simplexml_import_dom($fluidxml->dom());
一个示例数组可以是
$array = [ 'doc' => [
'fruit' => 'orange',
'cake' => [
'@id' => '123',
'@' => 'tiramisu' ],
[ 'pasta' => 'matriciana' ],
[ 'pasta' => 'boscaiola' ]
] ];

下面是php 5.2代码，将数组的任何深度转换为xml文档:
Array
(
['total_stud']=> 500
[0] => Array
(
[student] => Array
(
[id] => 1
[name] => abc
[address] => Array
(
[city]=>Pune
[zip]=>411006
)
)
)
[1] => Array
(
[student] => Array
(
[id] => 2
[name] => xyz
[address] => Array
(
[city]=>Mumbai
[zip]=>400906
)
)
)
)
生成的XML如下所示:
<?xml version="1.0"?>
<student_info>
<total_stud>500</total_stud>
<student>
<id>1</id>
<name>abc</name>
<address>
<city>Pune</city>
<zip>411006</zip>
</address>
</student>
<student>
<id>1</id>
<name>abc</name>
<address>
<city>Mumbai</city>
<zip>400906</zip>
</address>
</student>
</student_info>
PHP代码片段
<?php
// function defination to convert array to xml
function array_to_xml( $data, &$xml_data ) {
foreach( $data as $key => $value ) {
if( is_array($value) ) {
if( is_numeric($key) ){
$key = 'item'.$key; //dealing with <0/>..<n/> issues
}
$subnode = $xml_data->addChild($key);
array_to_xml($value, $subnode);
} else {
$xml_data->addChild("$key",htmlspecialchars("$value"));
}
}
}
// initializing or creating array
$data = array('total_stud' => 500);
// creating object of SimpleXMLElement
$xml_data = new SimpleXMLElement('<?xml version="1.0"?><data></data>');
// function call to convert array to xml
array_to_xml($data,$xml_data);
//saving generated xml file;
$result = $xml_data->asXML('/file/path/name.xml');
?>
本代码段中使用的SimpleXMLElement::asXML文档
以上答案大部分是正确的。然而，我想出了这个答案，它解决了array_walk_recursive的兼容性问题，也解决了数值键的问题。它也通过了我做的所有测试:
function arrayToXML(Array $array, SimpleXMLElement &$xml) {
foreach($array as $key => $value) {
// None array
if (!is_array($value)) {
(is_numeric($key)) ? $xml->addChild("item$key", $value) : $xml->addChild($key, $value);
continue;
}
// Array
$xmlChild = (is_numeric($key)) ? $xml->addChild("item$key") : $xml->addChild($key);
arrayToXML($value, $xmlChild);
}
}
我还为此添加了一个测试类，你可能会发现有用:
class ArrayToXmlTest extends PHPUnit_Framework_TestCase {
public function setUp(){ }
public function tearDown(){ }
public function testFuncExists() {
$this->assertTrue(function_exists('arrayToXML'));
}
public function testFuncReturnsXml() {
$array = array(
'name' => 'ardi',
'last_name' => 'eshghi',
'age' => 31,
'tel' => '0785323435'
);
$xmlEl = new SimpleXMLElement('<root/>');
arrayToXml($array, $xmlEl);
$this->assertTrue($xmlEl instanceOf SimpleXMLElement);
}
public function testAssocArrayToXml() {
$array = array(
'name' => 'ardi',
'last_name' => 'eshghi',
'age' => 31,
'tel' => '0785323435'
);
$expectedXmlEl = new SimpleXMLElement('<root/>');
$expectedXmlEl->addChild('name', $array['name']);
$expectedXmlEl->addChild('last_name', $array['last_name']);
$expectedXmlEl->addChild('age', $array['age']);
$expectedXmlEl->addChild('tel', $array['tel']);
$actualXmlEl = new SimpleXMLElement('<root/>');
arrayToXml($array, $actualXmlEl);
$this->assertEquals($expectedXmlEl->asXML(), $actualXmlEl->asXML());
}
public function testNoneAssocArrayToXml() {
$array = array(
'ardi',
'eshghi',
31,
'0785323435'
);
// Expected xml value
$expectedXmlEl = new SimpleXMLElement('<root/>');
foreach($array as $key => $value)
$expectedXmlEl->addChild("item$key", $value);
// What the function produces
$actualXmlEl = new SimpleXMLElement('<root/>');
arrayToXml($array, $actualXmlEl);
$this->assertEquals($expectedXmlEl->asXML(), $actualXmlEl->asXML());
}
public function testNestedMixArrayToXml() {
$testArray = array(
"goal",
"nice",
"funny" => array(
'name' => 'ardi',
'tel' =>'07415517499',
"vary",
"fields" => array(
'small',
'email' => 'ardi.eshghi@gmail.com'
),
'good old days'
),
"notes" => "come on lads lets enjoy this",
"cast" => array(
'Tom Cruise',
'Thomas Muller' => array('age' => 24)
)
);
// Expected xml value
$expectedXmlEl = new SimpleXMLElement('<root/>');
$expectedXmlEl->addChild('item0', $testArray[0]);
$expectedXmlEl->addChild('item1', $testArray[1]);
$childEl = $expectedXmlEl->addChild('funny');
$childEl->addChild("name", $testArray['funny']['name']);
$childEl->addChild("tel", $testArray['funny']['tel']);
$childEl->addChild("item0", "vary");
$childChildEl = $childEl->addChild("fields");
$childChildEl->addChild('item0', 'small');
$childChildEl->addChild('email', $testArray['funny']['fields']['email']);
$childEl->addChild("item1", 'good old days');
$expectedXmlEl->addChild('notes', $testArray['notes']);
$childEl2 = $expectedXmlEl->addChild('cast');
$childEl2->addChild('item0', 'Tom Cruise');
$childChildEl2 = $childEl2->addChild('Thomas Muller');
$childChildEl2->addChild('age', $testArray['cast']['Thomas Muller']['age']);
// What the function produces
$actualXmlEl = new SimpleXMLElement('<root/>');
arrayToXml($testArray, $actualXmlEl);
$this->assertEquals($expectedXmlEl->asXML(), $actualXmlEl->asXML());
}
}
// 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;
}

我的答案，拼凑别人的答案。这应该可以纠正无法补偿数字键的错误:
function array_to_xml($array, $root, $element) {
$xml = new SimpleXMLElement("<{$root}/>");
foreach ($array as $value) {
$elem = $xml->addChild($element);
xml_recurse_child($elem, $value);
}
return $xml;
}
function xml_recurse_child(&$node, $child) {
foreach ($child as $key=>$value) {
if(is_array($value)) {
foreach ($value as $k => $v) {
if(is_numeric($k)){
xml_recurse_child($node, array($key => $v));
}
else {
$subnode = $node->addChild($key);
xml_recurse_child($subnode, $value);
}
}
}
else {
$node->addChild($key, $value);
}
}
}
array_to_xml()函数假定数组首先由数字键组成。如果数组有一个初始元素，则可以从array_to_xml()函数中删除foreach()和$elem语句，只传递$xml。
