如何使用 php 用正确的编码重写这个 xml 文件？

Question

我想用php重写一个没有编码字符的xml文件。

我的 xml 文件如下所示：

<order>
<orderId>9132</orderId>
<statusId>3</statusId>
<adminUrl>www.floros24.gr/wp-admin/post.php?post=9132&amp;action=edit</adminUrl>
<status>&#x39F;&#x3BB;&#x3BF;&#x3BA;&#x3BB;&#x3B7;&#x3C1;&#x3C9;&#x3BC;&#x3AD;&#x3BD;&#x3B7;</status>
<dateCreated>2021-06-26T22:24:56+03:00</dateCreated>
<dateCompleted>2021-06-28T10:56:05+03:00</dateCompleted>
<dateModified/>
<datePaid>2021-06-28T10:56:05+03:00</datePaid>
<paymentMethodId>1</paymentMethodId>
<paymentMethod>&#x391;&#x3BD;&#x3C4;&#x3B9;&#x3BA;&#x3B1;&#x3C4;&#x3B1;&#x3B2;&#x3BF;&#x3BB;&#x3AE;</paymentMethod>
<userId>-1</userId>
<notes/>
<total>53.17</total>
<vatAmount>12.76</vatAmount>
<amount>65.93</amount>
<billing>
  <firstName>&#x395;&#x3C5;&#x3B1;&#x3B3;&#x3B3;&#x3B5;&#x3BB;&#x3AF;&#x3B1;</firstName>
  <lastName>&#x3A4;&#x3C1;&#x3B9;&#x3B1;&#x3BD;&#x3C4;&#x3B1;&#x3C6;&#x3CD;&#x3BB;&#x3BB;&#x3BF;&#x3C5;</lastName>
  <address>25&#x3B7;&#x3C2; &#x39C;&#x3B1;&#x3C1;&#x3C4;&#x3AF;&#x3BF;&#x3C5; 23</address>
  <city>&#x3A3;&#x3AF;&#x3BD;&#x3B4;&#x3BF;&#x3C2;</city>
  <postcode>57400</postcode>
  <state>B</state>
  <country>GR</country>

如何解决编码字符的问题？ 有什么办法可以用php重写文件吗？

谢谢。

编辑：

这是我的代码，它获取一个 xml 文件，然后根据基本 xml 文件中有多少不同的订单 ID 将其拆分为多个部分。上面的 XML 是这段代码处理的 XML 之一，为什么这段代码会返回那些带有编码字符的 xml 文件？ （编码的字符是 html 实体。）。

代码如下：

    <?php
// Prevent logging.
error_reporting(0);

$xmlFilepath = 'Final.xml';

function formatXML($xmlFilepath) {
    $filename = 'info.txt';
    $contents = file($filename);
    $loadxml = simplexml_load_file($xmlFilepath);
    
    //$key = $loadxml->order[2]->orderId;
    $count = $loadxml->order;

    // The [i] counter for $key(orderId + name of .xml files).

    foreach($count as $plus){

        $counter = $counter + 1;

    }

for($i = 0; $i <= $counter; $i++){
    $key = $loadxml->order[$i]->orderId;
    $v = $i;
    foreach($contents as $lines){   
            if ( preg_match_all( "/[^0-9]{$key}[^0-9]/", $lines ) ){
                
                echo "{$key} found! <br>";

            } elseif (preg_match_all( "/[^0-9]{$key}[^0-9]/", $lines) != true ) {
                
                $x = false;

                while($x == false) {

                    $orderset = $loadxml->order[$v];

                            // ORIGINAL
                            $formatxml = new SimpleXMLElement($orderset->saveXML());
                            $formatxml->saveXML("/home/floros24/public_html/farmaxml/orders/{$key}.xml"); // Save as {key.xml}.

                            // Open the file to get existing content
                            $current = file_get_contents($filename);
                            // Append a new person to the file
                            $current .= " {$key}";
                            // Write the contents back to the file
                            file_put_contents($filename, $current);

                    $x = true;
                    
                    }
                }
            }
    } // <--- Closing For[i].
} // <--- Closing of the Function.

formatXML($xmlFilepath);

?>

没有正确测试它，但这可能有效。不知道你要找什么样的结果，所以把它做成一个简单的关联数组

<?php
    
    $content = 'your xml content';
    
    $decode = static function(SimpleXMLElement $node) use (&$decode) {
        if($node->children()->count() > 0) {
            $result = [];
    
            foreach($node->children() as $child) {
                $result[$child->getName()] = $decode($child);
            }
        } else {
            $result = html_entity_decode((string) $node);
        }
    
        return [$node->getName() => $result];
    };
    
    $xml = simplexml_load_string(
        $content,
        SimpleXMLElement::class,
        LIBXML_NOERROR |  LIBXML_ERR_NONE,
    );
    
    var_dump($decode($xml));

输出：
