我發現了這個： https ://www.php.net/manual/en/class.simplexmlelement.php#107869
但是，在我的情況下$errors，該行中顯示的數組$errors = libxml_get_errors();始終為空。所以那個片段沒有幫助。此外，我還收到以下警告：
PHP Warning: DOMDocument::loadXML(): Input is not proper UTF-8, indicate encoding !\nBytes: 0x85 0x20 0x20 0x20 in Entity, line: 1 in /var/www/html/radio/metadata.php on line 6
[Fri Jan 24 18:56:12.290661 2020] [php7:warn] [pid 17910] [client 130.xxx.xxx.xxx:xxxxx] PHP Warning: simplexml_import_dom(): Invalid Nodetype to import in /var/www/html/radio/metadata.php on line 12
utf8_encode()無論如何，我設法通過在將字符串提供給 SimpleXMLElement 構造函數之前對字符串進行編碼來克服這種混亂的情況。
我生成的“測試” php 文件是：
<?php
// header('Content-type: application/json');
$output = file_get_contents('error.xml.bak');
$output = utf8_encode($output);
$doc = new DOMDocument('1.0', 'utf-8');
$doc->loadXML($output);
var_dump($output);
$errors = libxml_get_errors();
var_dump($errors);
$xml = simplexml_import_dom($doc);
// $xml = new SimpleXMLElement($output, LIBXML_NOERROR|LIBXML_ERR_NONE) or die('Something is wrong');
var_dump($xml);
?>
這導致以下打印輸出沒有任何錯誤或警告......

注意：有問題的角色仍然存在！ \u0085但正確編碼所以我想這就是為什么它不再是一個問題......
我還使用 SimpleXMLElement 構造函數嘗試了以前版本的代碼：
<?php
$output = file_get_contents('error.xml.bak');
$output = utf8_encode($output);
$xml = new SimpleXMLElement($output, LIBXML_NOERROR|LIBXML_ERR_NONE) or die('Something is wrong');
echo json_encode($xml);
?>
這也按預期工作：
{"CURRENTLISTENERS":"1","PEAKLISTENERS":"3","MAXLISTENERS":"5000","REPORTEDLISTENERS":"1","AVERAGETIME":"1","SERVERGENRE":"public","SERVERURL":"http:\/\/www.virtualdj.com\/","SERVERTITLE":"wolf","SONGTITLE":"BARRY WHITE - YOU'RE THE FIRST,THE LAST \u0085 ","SONGURL":{},"IRC":"wolf","ICQ":"wolf","AIM":"wolf","WEBHITS":"80","STREAMHITS":"6","STREAMSTATUS":"1","BITRATE":"96","CONTENT":"audio\/mpeg","VERSION":"1.9.8","WEBDATA":{"INDEX":"0","LISTEN":"0","PALM7":"6","LOGIN":"0","LOGINFAIL":"0","PLAYED":"0","COOKIE":"0","ADMIN":"1","UPDINFO":"1","KICKSRC":"0","KICKDST":"0","UNBANDST":"0","BANDST":"0","VIEWBAN":"0","UNRIPDST":"0","RIPDST":"0","VIEWRIP":"0","VIEWXML":"69","VIEWLOG":"0","INVALID":"3"},"LISTENERS":{"LISTENER":{"HOSTNAME":"78.129.222.56","USERAGENT":"curl\/7.29.0","UNDERRUNS":"0","CONNECTTIME":"216","POINTER":"0","UID":"2"}},"SONGHISTORY":{"SONG":{"PLAYEDAT":"1579791561","TITLE":"BARRY WHITE - YOU'RE THE FIRST,THE LAST \u0085 "}}}
注意最后的 \u0085 ...
