How to say "Or" in a REGEX pattern?

I'm trying to find all videos in a piece of html:

preg_match_all('[<iframe*]', $this->textile_text, $video_matches);

I'm using PHP.

Right now I am only matching iframe tags, I need to also look for embed and object tags. Those are the only ways I can think of videos being embedded in html.

How can I say "or" so this would work?

preg_match_all('[<iframe*] OR [<embed*] OR [<object*]', $this->textile_text, $video_matches);

Also if anyone can think of a better REGEX pattern to detect videos, that would be great because mine is quite elementary.

EDIT

This produced this output:

preg_match_all("(iframe|embed|object)", $this->textile_text, $video_matches);


Array
(
    [0] => Array
        (
            [0] => object
            [1] => embed
            [2] => embed
            [3] => embed
            [4] => embed
            [5] => object
            [6] => iframe
            [7] => embed
            [8] => iframe
            [9] => iframe
            [10] => embed
            [11] => iframe
            [12] => iframe
            [13] => embed
            [14] => iframe
            [15] => iframe
            [16] => embed
            [17] => iframe
            [18] => iframe
            [19] => embed
            [20] => iframe
            [21] => iframe
            [22] => embed
            [23] => iframe
            [24] => iframe
            [25] => embed
            [26] => iframe
        )

)

Should have been:

Array
(
    [0] => Array
        (
            [0] => <iframe
            [1] => <iframe
            [2] => <iframe
            [3] => <iframe
            [4] => <iframe
            [5] => <iframe
            [6] => <iframe
            [7] => <embed        
         )

)

I think this will get you what you need.

(iframe|embed|object)

This should match one of those three words according to the documentation. I however do not have access to the PHP specific versions of reg-ex to give this a go.
