去掉 来自HTML内容的标记

Question

我试图在网站上显示一个干净的段落，但由于内容中间的<p></p>我没有得到预期的输出。我尝试了以下但没有一个工作，我仍然得到<p></p>我的内容。

$story = "<p>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p><p>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p>";


 1. $story = strip_tags($story, '<p>');
 2. $story=str_ireplace('<p>','',$story);
 3. $story=str_ireplace('</p>','',$story);
 4. $story = preg_replace('/<p\b[^>]*>(.*?)<\/p>/i', '', $story);

我在代码中遗漏了什么吗？我的预期产量是

答案：自16世纪以来，Lorem Ipsum一直是业界标准的虚拟文本，当时一个未知的打印机拿了一个类型的厨房，并拼写它制作一个类型的样本书。自16世纪以来，Lorem Ipsum一直是业界标准的虚拟文本，当时一台未知的打印机采用了类型的厨房，并将其拼凑成一本类型的样本。

Answer 1

用str_replace()尝试这种方式

<?php
$story = "<p>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p><p>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p>";
$result = str_replace(['<p>','</p>'],['',''],$story);
echo $result;
?>

或者使用https://3v4l.org/nllPP删除所有标记，顺便说一句，您可以使用此方法指定allowable_tags

strip_tags()

Answer 2

PHP具有内置函数来从字符串中删除HTML标记。最好使用$result = strip_tags($story); 而不是strip_tags()，这是一个例子

str_replace()

Answer 3

使用

     $story = "<p>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p><p>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p>";
;
        $a = strip_tags($story);
        $b = strip_tags($story, "<strong><em>"); // can also pass the tags that you don't want to remove

函数。

str_ireplace()

Answer 4

$story = "<p>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p><p>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p>";

echo $text=str_ireplace('<p>','',$story);

有一个内置函数，删除php中的所有html标签。用strip_tags（）
