How to format the entered text in the database?

Question

PHP

There is a form with which the user changes the base text and then it is displayed on the page. How to arrange it beautifully?
I can keep the custom formatting, but the problem is that the text itself is there <img src="">and then there will be no picture, only the tag will remain. Initially, everything in the database was tagged, but I don't think that's good.
Are there any other options?

Answer 1

Let's say you have a page with textarea, the user enters the formatting <.i>, <.b>, etc. there. Clicks on the button and the form is sent to the php handler:

$text = $_GET['text'];
$text = strip_tags($text, '<i><b>');

strip tags removes all tags from the first argument, the second argument is the tags that should not be removed.
