如何將PHP字符串讀取爲HTML

Question

我有一個PHP文件用於生成HTML文件。這是這個過程：

$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"); 

該吐出包含以下元素的HTML文件：

<div>This is a &lt;br&gt; test</div> 

也就是說，<br>標記獲取實際的HTML轉換爲<br>。我已經嘗試了所有的這些方法來取消轉義的字符串：

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"); 

，但他們所有的產品：

This is a <br> test

還有什麼能做些什麼來讓HTML標記來正確顯示爲HTML？

Answer 1

所以我發現正是我在尋找：

$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"); 

Answer 2

你可以試試這個：

<?php echo html_entity_decode("this is <br> test."); ?> 

Answer 3

<p>This is a <br /> test</p>是包含一個文本節點，br元素，另一個文本節點的p元素。

要使用PHP的XML作家正確做到這一點：

$element = $document->createElement('p'); 

$element->appendChild($document->createTextNode('This is a ')); 
$element->appendChild($document->createElement('br')); 
$element->appendChild($document->createTextNode(' test')); 

$document->appendChild($element);
