How to remove full HTML entities/blocks with PHP

I am trying to remove html <video> and <iframe> tags from my wordpress theme so that none of the contents within the block will be shown.

Meaning, I don't want to just remove the tags but all of the data inbetween the tags. I am guessing this can be done with some string manipulation, but I am not sure how the syntax would work or how to write it out.

here is my code 

function custom_trim_excerpt($text) {
    global $post;


    if ('' == $text) {
        $text = get_the_content('');
        $text = apply_filters('the_content', $text);
        $text = str_replace('\]\]\>', ']]&gt;', $text);
        $text = preg_replace('@<script[^>]*?>.*?</script>@si', '', $text);
        $text = strip_tags($text, '<p>,<a>,<em>,<blockquote>,<iframe>');
        $excerpt_length = 15;

        $type = get_post($post);

        if($type->post_type == "post" ) {
          $excerpt_length =7; 
        }

        $words = explode(' ', $text, $excerpt_length + 1);
        if (count($words) > $excerpt_length) {
            array_pop($words);
            array_push($words, '...');
            $text = implode(' ', $words);
        }
    }
    return $text;
}

I haven't put any of the code in here to attempt it, this is just the block I would like to insert it into. So that any of the text is stripped of these tags and the content in between them.

Any help/advice is greatly appreciated! Thanks!
