parsing out html (ereg coding)

[Anon]

I'm have these blobs in a database and
I want to be able to pull an array of keywords from them and I was wondering if anyone has a pre-made script to remove all html tags.
Thanks,

PHP already has a function to do this.

$foo = strip_tags($foo);

Will remove all HTML from $foo.

Now if you want to allow certain tags, like bold and italic, for example strip_tags accepts an argument to do so:

$foo = strip_tags($foo,"<b>,<i>");

Hope that helped.
