php - Strip all HTML tags, except allowed

Question

I've seen a lot of expressions to remove a specific tag (or many specified tags), and one to remove all but one specific tag, but I haven't found a way to remove all except many excluded (i.e. all except p, b, i, u, a, ul, ol, li) in PHP. I'm far from good with regex, so I'd need a hand. :) Thanks!

Answer 1

you can do this by usingstrip_tags function

? strip_tags — Strip HTML and PHP tags from a string

 strip_tags($contant,'tag you want to allow');

like

  strip_tags($contant,'<code><p>');
