我正在嘗試讀取 .php 中的 SimpleXMLElement 以補充搜索功能。我通過請求從一個名為 openthesaurus.de 的德語同義詞 API 獲取 XML file_get_contents。然后，我將收到的元素轉換為 SimpleXMLElement 并嘗試讀取每個元素的屬性term。（我知道下面的代碼只關注synset['0']）。這樣做是為了保持簡單。我的 .php 看起來像這樣 $url = "https://www.openthesaurus.de/synonyme/search?q=". $keyword. "&format=text/xml"; $options = array('http' => array( 'method' => 'POST', 'header' => 'user_agent: my-site.xyz', ) ); $context = stream_context_create($options); $recive = file_get_contents($url, false, $context); if (($recieve = file_get_contents($url))===false){ echo "Error fetching XML\n"; } else { libxml_use_internal_errors(true); $syn = new SimpleXMLElement($recieve); if (!$syn) { echo "Error loading XML\n"; foreach(libxml_get_errors() as $error) { echo "\t", $error->message; } } else { echo "content: <br>"; foreach($syn->synset[0]->term as $value){ echo $value. "<br>"; } } }xml 看起來像這樣：<matches> <metaData> <apiVersion content="0.1.3"/> <warning content="WARNING -- this XML format may be extended without warning"/> <copyright content="Copyright (C) 2019 Daniel Naber (www.danielnaber.de)"/> <license content="Creative Commons Attribution-ShareAlike 4.0 or GNU LESSER GENERAL PUBLIC LICENSE Version 2.1"/> <source content="https://www.openthesaurus.de"/> <date content="Sat Jun 27 09:48:33 CEST 2020"/> </metaData>不幸的是，除了中斷之外，.php 沒有輸出任何內容。我也嘗試過通過 print_r 輸出，但這也沒有幫助。但是 if 條件表明empty($value)該條件$value不為空。

SimpleXMLElement我和這個家庭的任何人都不熟悉SimpleXML，但如果你改變以下內容
foreach($syn->synset[0]->term as $value){
echo $value. "<br>";
}
到
foreach( $syn->synset as $obj ){
foreach( $obj->term as $arr ){
foreach( $arr->attributes() as $attr => $value ) echo $attr . ' ' . $value .'<br />';
}
}
或者，更全面地說：
<?php
$keyword='kopf'; # for example...
$url = "https://www.openthesaurus.de/synonyme/search?q=". $keyword. "&format=text/xml";
$options = array('http' =>
array(
'method' => 'POST',
'header' => 'user_agent: my-site.xyz',
)
);
$context = stream_context_create( $options );
$recive = file_get_contents( $url, false, $context );
if( ( $recieve = file_get_contents( $url ) )===false ){
echo "Error fetching XML\n";
} else {
libxml_use_internal_errors(true);
$syn = new SimpleXMLElement( $recieve );
if (!$syn) {
echo "Error loading XML\n";
foreach(libxml_get_errors() as $error) {
echo "\t", $error->message;
}
} else {
foreach( $syn->synset as $obj ){
foreach( $obj->term as $arr ){
foreach( $arr->attributes() as $attr => $value ) echo $attr . ' ' . $value .'<br />';
}
}
}
}
?>
