Answer 1

用 str_replace()

试试这个方法

<?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;
?>

OR with strip_tags() 删除所有标签，顺便说一句，用这个方法你可以指定 allowable_tags

$result = strip_tags($story);

Answer 2

PHP 具有从字符串中删除 HTML 标签的内置函数。最好使用strip_tags()而不是str_replace()，这里有一个例子

     $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

Answer 3

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 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;

有一个内置函数可以删除 php 中的所有 html 标签。 strip_tags()

从 HTML 内容中删除 <p> 标签

Remove <p> tag from HTML content

php

preg-replace

strip-tags
