php - 似乎无法摆脱 API 返回的不需要的标签

Question

我需要删除从 Petfinder API 返回的描述中的所有 HTML 标记，但我似乎无法弄清楚如何。

$data['description']保存返回的描述。我在源文件中看到的是这样的......

<div>some text that gets returned</div>

我试过用strip_tags，我试过用html_entity_decode，但标签不会消失！

我需要剥离标签，以便截断描述。

有人有想法么？

$data['description'] = (string)$pet->description;

$description = $data['description'];
$description = htmlentities($description);
$description = html_entity_decode($description);
$description = strip_tags($description);

$description = substr($data['description'],0,300);
$description = substr($description,0,strrpos($description,' '));
$description = $description."...";

echo "<span style='text-align: justify; margin: 10px 0px;'>".$description."</span>";

Answer 1

问题是你先跑htmlentities。在这之后strip_tags不能再工作了。

只需这样做：

$test = '<div>some text that gets returned</div>';
echo strip_tags($test);

硬核方式：

$doc = new DOMDocument();
$doc->loadHTML('<div>some text that gets returned</div>');
$items = $doc->getElementsByTagName('div');
$content = $items->item(0)->nodeValue;
echo $content;

Answer 2

问题是您在处理过程中再次使用原始输入：

$description = $data['description'];
$description = htmlentities($description);
$description = html_entity_decode($description);
$description = strip_tags($description);

$description = substr($data['description'],0,300);
                      ^^^^^^^^^^^^^^^^^^^^ All previous changes undone!
$description = substr($description,0,strrpos($description,' '));
$description = $description."...";

除此之外，@redreggae 是对的，你只需要strip_tags.
