When I use the internal function strip_tags() to remove a tag html, it removes only the tag itself <p></p>. But I would like to see its contents removed as well <p>teste</p>. Any idea?

php

  • It is not better to use JavaScript?

  • In this specific case I need to use only PHP. It is only a maintenance in an existing class. @Shutupmagda

You can use preg_replace

$yourString = 'Hello <div>Planet</div> Earth. This is some <span class="foo">sample</span> content! <p>Hello</p>';
$regex = '/<[^>]*>[^<]*<[^>]*>/';
echo preg_replace($regex, '', $yourString);

This will return:

Hello Earth. This is some content!

If you need to remove a specific tag, it can be done this way:

echo preg_replace('/<h1[^>]*>([\s\S]*?)<\/h1[^>]*>/', '', 'Hello<h1>including this content</h1> There !!');

This will return

Hello There
