我有一个用于生成HTML文件的PHP文件。这是一个过程:
$document = new DomDocument;
$document->preserveWhiteSpace = false;
$document->validateOnParse = true;
$document->loadHTML(file_get_contents("http://www.example.com/base.html"));
$testNode = $document->createElement("div", "This is a <br> test");
$document->appendChild($testNode);
$document->saveHTMLFile("output.html");
这会吐出一个包含以下元素的HTML文件:
<div>This is a <br> test</div>
也就是说,<br>
代码会在实际HTML中转换为<br>
。我已经尝试了所有这些方法来解开字符串:
htmlspecialchars("This is a <br> test");
rawurldecode("This is a <br> test");
urldecode("This is a <br> test");
function decodeashtml($str) {
$str = preg_replace("/%u([0-9a-f]{3,4})/i","&#x\\1;",urldecode($str));
return html_entity_decode($str,null,'UTF-8');;
}
decodeashtml("This is a <br> test");
但他们都产生了:
This is a <br> test
我还能做些什么来让HTML标签正确显示为HTML?

你可以试试这个:
<?php echo html_entity_decode("this is <br> test."); ?>
答案 1 :(得分:1)
<p>This is a <br /> test</p>
是一个p
元素,包含文本节点,br
元素和另一个文本节点。
使用PHP的XML编写器正确执行此操作:
$element = $document->createElement('p');
$element->appendChild($document->createTextNode('This is a '));
$element->appendChild($document->createElement('br'));
$element->appendChild($document->createTextNode(' test'));
$document->appendChild($element);

所以我找到了我正在寻找的东西:
$document = new DomDocument;
$document->preserveWhiteSpace = false;
$document->validateOnParse = true;
$document->loadHTML(file_get_contents("http://www.example.com/base.html"));
$newDiv = $document->createElement("div");
$fragment = $document->createDocumentFragment();
$fragment->appendXML("<p>I can write<br/>my HTML here.</p>");
$newDiv->appendChild($fragment);
$document->appendChild($newDiv);
$document->saveHTMLFile("output.html");
