Do not use this function directly, use wp_embed_register_handler() instead.

This function should probably also only be used for sites that do not support oEmbed.

An internal ID/name for the handler. Needs to be unique.

$regexstringrequired

The regex that will be used to see if this handler should be used for a URL.

$callbackcallablerequired

The callback function that will be called if the regex is matched.

$priorityintoptional

Used to specify the order in which the registered handlers will be tested.
Lower numbers correspond with earlier testing, and handlers with the same priority are tested in the order in which they were added to the action.

Default:10

Source

public function register_handler( $id, $regex, $callback, $priority = 10 ) {
	$this->handlers[ $priority ][ $id ] = array(
		'regex'    => $regex,
		'callback' => $callback,
	);
}
