如何在 PHP 中只保留指定的 HTML 标签？

Keeping Only Specified HTML Tags

Seeking a solution to remove all HTML tags except for specific allowed ones in PHP? Here's your answer.

PHP offers a powerful function called strip_tags that enables you to strip unwanted HTML and PHP tags from a string. To retain only specific tags, you can use the optional second parameter of this function to define the list of allowed tags.

<code class="php">strip_tags($content, '&lt;code&gt;&lt;p&gt;');</code>

In this example, the strip_tags function will strip all tags except and

from the $content variable. The result will be a string containing only the allowed tags and their content.

By utilizing this method, you can efficiently remove all unwanted HTML tags and maintain the integrity of selected tags in your PHP code, ensuring that specific elements remain intact for your application's functionality.
