Question

我尝试使用Walmart API显示有关产品的一些信息。

API返回一个json对象，我将其转换为常规数组，并使用echo来显示此数据。

问题是，当我从API获取longDescription变量时，它包含HTML - 这很好，但它没有被渲染，而是将它全部显示为纯文本。这是我的代码：

echo "<p id='longDescription'>";
    echo $obj['longDescription'];
echo "</p>";

这是$obj['longDescription']变量中包含的内容：

我不确定从哪里开始或做什么，我以前从未遇到过这个问题。

如何将此变量输出为呈现的HTML？

Answer 1

尝试使用 html_entity_decode（）
Convert all HTML entities to their applicable characters

更确切地说，此函数解码所有实体（包括所有实体）数字实体）a）必然对所选择的有效文档类型 - 即，对于XML，此函数不解码命名可能在某些DTD中定义的实体 - 和b）其特征或字符在与所选字符集相关联的编码字符集中编码并在所选文档类型中允许。所有其他实体保持原样。

Answer 2

输出可能是用

呈现的

<

输出“＆lt;”。这很可能是你的问题。

您可以使用php函数

htmlspecialchars_decode()

希望这有助于：）

Answer 3

为了呈现 html，您必须对其进行解码。

这里我提到了一些解码它的功能。

wp_specialchars_decode() 如果您使用的是 WordPres。
htmlspecialchars_decode() 普通 PHP 函数。
html_entity_decode() 也是，普通的 PHP 函数。

解决方案：

<?php 
     // This work for me:
     echo wp_specialchars_decode($your_html_code, ENT_QUOTES);

     // try this if above code doesn't work
     // echo htmlspecialchars_decode($your_html_code);
     // try this if above code doesn't work
     // echo html_entity_decode($your_html_code, ENT_HTML5);
?>

其余两个函数的灵感来自 @Roy Bogado 和 @Firelumet 的回答。

PHP回显，HTML标记不呈现HTML，显示为明文
