Question

我在这里和网络的其他部分进行了搜索，我找不到任何帮助。

我收到了curl_exec的回复。响应是一个名为$ output的XML字符串。

echo '<pre>' . htmlentities($output) . '</pre>';

给出：

<?xml version="1.0" encoding="utf-8"?>
<RESPONSE>
  <FIELDS>
    <FIELD KEY="status">1</FIELD>
    <FIELD KEY="auth_code">DEMO43</FIELD>
    <FIELD KEY="auth_response">APPROVED</FIELD>
    <FIELD KEY="avs_code">X</FIELD>
    <FIELD KEY="cvv2_code"> </FIELD>
    <FIELD KEY="order_id">12345678900015</FIELD>
    <FIELD KEY="reference_number">47210</FIELD>
    <FIELD KEY="error" />
    <FIELD KEY="available_balance" />
    <FIELD KEY="is_partial">0</FIELD>
    <FIELD KEY="partial_amount">0</FIELD>
    <FIELD KEY="partial_id" />
    <FIELD KEY="original_full_amount" />
    <FIELD KEY="outstanding_balance">0</FIELD>
  </FIELDS>
</RESPONSE>

我需要提取具体信息，例如与“auth_code”相关联的值（即：DEMO43）。

经过几个小时徒劳无功的搜索，我需要帮助。如何将此数据转换为关联数组，如：

$array = ('status'=>'1','auth_code'=>'DEMO43' ... etc) ?

试试这个

$string = '<?xml version="1.0" encoding="utf-8"?>
<RESPONSE>
  <FIELDS>
    <FIELD KEY="status">1</FIELD>
    <FIELD KEY="auth_code">DEMO43</FIELD>
    <FIELD KEY="auth_response">APPROVED</FIELD>
    <FIELD KEY="avs_code">X</FIELD>
    <FIELD KEY="cvv2_code"> </FIELD>
    <FIELD KEY="order_id">12345678900015</FIELD>
    <FIELD KEY="reference_number">47210</FIELD>
    <FIELD KEY="error" />
    <FIELD KEY="available_balance" />
    <FIELD KEY="is_partial">0</FIELD>
    <FIELD KEY="partial_amount">0</FIELD>
    <FIELD KEY="partial_id" />
    <FIELD KEY="original_full_amount" />
    <FIELD KEY="outstanding_balance">0</FIELD>
  </FIELDS>
</RESPONSE>';


$ARR_OUTPUT = array();

$dom = new DOMDocument();
$dom->loadXML($string);
$searchNode = $dom->getElementsByTagName( "FIELD" ); 
foreach( $searchNode as $searchNode ) 
{
    $key = $searchNode->getAttribute('KEY');
    $value = $searchNode->nodeValue; 
    $ARR_OUTPUT[$key]=$value;
}
echo "<pre>";
print_r($ARR_OUTPUT);

输出：

Array
(
    [status] => 1
    [auth_code] => DEMO43
    [auth_response] => APPROVED
    [avs_code] => X
    [cvv2_code] =>  
    [order_id] => 12345678900015
    [reference_number] => 47210
    [error] => 
    [available_balance] => 
    [is_partial] => 0
    [partial_amount] => 0
    [partial_id] => 
    [original_full_amount] => 
    [outstanding_balance] => 0
)

PHP和XML属性
