Filtering the $allowedtags global in WordPress

I'm trying to filter the $allowedtags global in WordPress so that users can submit certain HTML elements only in comments.

This is how I'm currently doing it:

function my_allowed_tags() {
    global $allowedtags;
    $allowedtags['pre'] = array( 'style' => array() );
}
add_action( 'init', 'my_allowed_tags' );

This now allows the use of <pre> tags in comments along with a default list of tags that are already allowed by $allowedtags such as <p>, <a>, <img> etc.

How can I initialise the $allowedtags global so that no tags are allowed by default?

Add a filter which resets the global to an empty array before your current action fires.

function reset_allowed_tags() {
    global $allowedtags;
    $allowedtags = array();
}
add_action('init', 'reset_allowed_tags', 0);
