I’m try in this mode, but not working. Where is the error?

if ( isset( $_COOKIE[ 'ims_message_' . COOKIEHASH ] ) ) {
$messages = array(
'1' => __( 'Carrello aggiornato con successo', 'ims' ),
'2' => __( 'Aggiornamento con successo', 'ims' ),
);
$this->message = $messages[ $_COOKIE[ 'ims_message_' . COOKIEHASH ] ];
if ($messages[ $_COOKIE[ 'ims_message_' . COOKIEHASH ]] == 'true' && $messages == '1' ) {
wp_redirect( 'http://www.example.com', 301 ); exit;  
}
