特殊字符 0x85使 PHP 的 SimpleXMLElement 崩溃

我发现了这个： https ://www.php.net/manual/en/class.simplexmlelement.php#107869但是，在我的情况下$errors，该行中显示的数组$errors = libxml_get_errors();始终为空。所以那个片段没有帮助。此外，我还收到以下警告：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 12utf8_encode()无论如何，我设法通过在将字符串提供给 SimpleXMLElement 构造函数之前对字符串进行编码来克服这种混乱的情况。我生成的“测试” 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);?>这导致以下打印输出没有任何错误或警告......string(3396) "]>13500011publichttp://www.virtualdj.com/wolfBARRY WHITE - YOU'RE THE FIRST,THE LAST  wolfwolfwolf806196audio/mpeg1.9.800600001100000000690378.129.222.56curl/7.29.00216021579791561 " array(0) { } object(SimpleXMLElement)#2 (22) { ["CURRENTLISTENERS"]=> string(1) "1" ["PEAKLISTENERS"]=> string(1) "3" ["MAXLISTENERS"]=> string(4) "5000" ["REPORTEDLISTENERS"]=> string(1) "1" ["AVERAGETIME"]=> string(1) "1" ["SERVERGENRE"]=> string(6) "public" ["SERVERURL"]=> string(25) "http://www.virtualdj.com/" ["SERVERTITLE"]=> string(4) "wolf" ["SONGTITLE"]=> string(64) "BARRY WHITE - YOU'RE THE FIRST,THE LAST  " ["SONGURL"]=> object(SimpleXMLElement)#3 (0) { } ["IRC"]=> string(4) "wolf" ["ICQ"]=> string(4) "wolf" ["AIM"]=> string(4) "wolf" ["WEBHITS"]=> string(2) "80" ["STREAMHITS"]=> string(1) "6" ["STREAMSTATUS"]=> string(1) "1" ["BITRATE"]=> string(2) "96" ["CONTENT"]=> string(10) "audio/mpeg" ["VERSION"]=> string(5) "1.9.8" ["WEBDATA"]=> object(SimpleXMLElement)#4 (20) { ["INDEX"]=> string(1) "0" ["LISTEN"]=> string(1) "0" ["PALM7"]=> string(1) "6" ["LOGIN"]=> string(1) "0" ["LOGINFAIL"]=> string(1) "0" ["PLAYED"]=> string(1) "0" ["COOKIE"]=> string(1) "0" ["ADMIN"]=> string(1) "1" ["UPDINFO"]=> string(1) "1" ["KICKSRC"]=> string(1) "0" ["KICKDST"]=> string(1) "0" ["UNBANDST"]=> string(1) "0" ["BANDST"]=> string(1) "0" ["VIEWBAN"]=> string(1) "0" ["UNRIPDST"]=> string(1) "0" ["RIPDST"]=> string(1) "0" ["VIEWRIP"]=> string(1) "0" ["VIEWXML"]=> string(2) "69" ["VIEWLOG"]=> string(1) "0" ["INVALID"]=> string(1) "3" } ["LISTENERS"]=> object(SimpleXMLElement)#5 (1) { ["LISTENER"]=> object(SimpleXMLElement)#7 (6) { ["HOSTNAME"]=> string(13) "78.129.222.56" ["USERAGENT"]=> string(11) "curl/7.29.0" ["UNDERRUNS"]=> string(1) "0" ["CONNECTTIME"]=> string(3) "216" ["POINTER"]=> string(1) "0" ["UID"]=> string(1) "2" } } ["SONGHISTORY"]=> object(SimpleXMLElement)#6 (1) { ["SONG"]=> object(SimpleXMLElement)#7 (2) { ["PLAYEDAT"]=> string(10) "1579791561" ["TITLE"]=> string(64) "BARRY WHITE - YOU'RE THE FIRST,THE LAST  " } } } 注意：有问题的角色仍然存在！ \u0085但正确编码所以我想这就是为什么它不再是一个问题......我还使用 SimpleXMLElement 构造函数尝试了以前版本的代码：<?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);?>这也按预期工作：{"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 ...
