PHP で XML に新しい要素を追加するときに属性を設定するにはどうすればよいですか。私のPHPコードは次のようなものです： 

 <?php
     $xml = simplexml_load_file ( 'log.xml' );

     $movies = $xml->addChild("time");
      // add attribut `value` here in tag time

     $user = $movies->addChild("user", "");
     // add attribut `id` here in tag user

     $action = $user->addChild("action","");
     // add attribut `value` here in tag action

     $action->addChild("table","customers");

     $action->addChild("table_id","1");

     echo $xml->saveXML( 'log.xml' );
 ?>

そして、出力を次のようにしたい：

// log.xml
<?xml version="1.0" encoding="utf-8"?>
<log>
<time value="2013-01-10 12:20:01">
    <user id="1">
        <action value="delete">
            <table>customer</table>
            <table_id>1</table_id>
        </action>   
        <action value="insert">
            <table>customer</table>
            <data>
                <nama>budi</nama>
            </data>
        </action>
        <action value="update">
            <table>customer</table>
            <table_id>1</table_id>
            <old_data>
                <nama>andi</nama>
            </old_data>
            <new_data>
                <nama>budi</nama>
            </new_data>
        </action>
    </user>
</time>
</log>

私を助けてください..私はxmlについて非常に新しいです

SimpleXMLElement::addAttribute を使用する — SimpleXML 要素に属性を追加する

編集：あなたのユースケース -

     $action = $user->addChild("action","");
     // add attribut `value` here in tag action
     $action->addAttribute('value','update'); // add this

     $action->addChild("table","customers");

     $action->addChild("table_id","1");

最良の例:

http://php.net/manual/en/simplexmlelement.addattribute.php

<?php

include 'example.php';

$sxe = new SimpleXMLElement($xmlstr);
$sxe->addAttribute('type', 'documentary');

$movie = $sxe->addChild('movie');
$movie->addChild('title', 'PHP2: More Parser Stories');
$movie->addChild('plot', 'This is all about the people who make it work.');

$characters = $movie->addChild('characters');
$character  = $characters->addChild('character');
$character->addChild('name', 'Mr. Parser');
$character->addChild('actor', 'John Doe');

$rating = $movie->addChild('rating', '5');
$rating->addAttribute('type', 'stars');

echo $sxe->asXML();

?>

SimpleXML を他のソリューションと組み合わせるのに 3 時間を費やし、最終的にこれを取得しました。それは機能し、役立つことを願っています。

$xml_data = new SimpleXMLElement('<?xml version="1.0"?><data></data>');

$arrXml = [
    "categories" => [
        'category' => [
            '@attributes' => [
                'id' => '123',
                'parent_id' => '12345'
            ],
            '@value' => 'Bikes'
        ]
    ],
    "properties" => [
        'property' => [
            'id' => '123',
            'categoryId' => '1',
            'name' => 'Color',
            'values' => [
                'value' => [
                    "id" => '1',
                    "name" => 'Black'
                ],
                'value' => [
                    "id" => '2',
                    "name" => 'White'
                ]
            ]
        ]
    ],
    "products" => [
        'products' => [
            'id' => '1231231',
            'categoryId' => '123',
            'model' => [
                    '@attributes' => [
                            'foo' => 'bar',
                    ],
                '@value' => 'Avalanche'
            ],
            'article' => '1.0 2011',
            'vendor' => 'GT',
        ]
    ]
];

array_to_xml($arrXml,$xml_data);

//saving generated xml file;
$result = $xml_data->asXML('test.xml');

// print $xml_data->asXML();

に行きます

<data>
<categories>
    <category id="123" parent_id="12345">Bikes</category>
</categories>
<properties>
    <property>
        <id>123</id>
        <categoryId>1</categoryId>
        <name>Color</name>
        <values>
            <value>
                <id>2</id>
                <name>White</name>
            </value>
        </values>
    </property>
</properties>
<products>
    <products>
        <id>1231231</id>
        <categoryId>123</categoryId>

        <article>1.0 2011</article>
        <vendor>GT</vendor>
    </products>
</products>

この関数で:

function array_to_xml( $data, &$xml_data ) {
        foreach( $data as $key => $value ) {
            if (!empty($value)) {
                if( is_array($value)) {
                    if (!empty($value["@attributes"])) {
                            $subnode = $xml_data->addChild($key, $value["@value"]);
                            foreach ($value["@attributes"] as $key1 => $val1) {
                                $subnode->addAttribute($key1, $val1);
                            }
                    } else if ($key == "@value") {
                        foreach ($value as $attr => $attrVal) {
                            $subnode = $xml_data->addChild("$attr", $attrVal);
                            array_to_xml($attrVal, $subnode);
                        }
                    } else {
                            if (!empty($value)) {
                                    $subnode = $xml_data->addChild($key);
                                    array_to_xml($value, $subnode);
                            }
                    }
                } else {
                        $xml_data->addChild("$key",$value);
                }
            }
        }
    }

使用するaddAttribute()

$movies->addAttribute('value','your value here');
$action->addAttribute('value','your value here');
$user->addAttribute('id','your value here');
