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']包含返回的说明。我在源文件中看到的是这样的......

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

我已尝试使用strip_tags，我已尝试使用html_entity_decode，但标签不会消失！

我需要剥离标记，以便我可以截断描述..

有人有什么想法吗？

$data['description'] = (string)$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

问题是你首先运行htmlentities。此后strip_tags无法再使用了。

简单地说：

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

问题是您在处理中途再次使用原始输入：

$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。

似乎无法摆脱API返回的不需要的标签
