Question

我试图在网站上显示干净的段落，但是由于内容中间的<p></p>，我没有得到预期的输出。我已经尝试了以下方法，但没有一个起作用，但我的内容仍在<p></p>周围。

$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);

我是否错过了代码中的任何内容？我的预期输出将是

答案：自1500年代以来，Lorem Ipsum一直是行业标准的伪文本，当时一位不知名的打印机拿起一个厨房，将其打乱成一本样本书。自1500年代以来，Lorem Ipsum一直是行业的标准伪文本，当时一位不知名的打印机拿来一个样板间，然后将其拼写成样本。

Answer 1

PHP具有内置功能，可从字符串中删除HTML标记。最好使用flutter doctor -v而不是strip_tags()，这是一个示例

str_replace()

Answer 2

使用str_ireplace()函数。

$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);

Answer 3

尝试使用str_replace()

<?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;
?>

或与strip_tags()一起删除所有标签，通过这种方法，您可以指定 allowable_tags

$result = strip_tags($story);

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>";

$story = strip_tags($story) ;
echo $story;
