domain.tld/?p=1234 → domain.tld/custom/permalink/?p=1234
domain.tld/?id=8&p=1234&str=str → domain.tld/custom/permalink/?id=8&p=1234&str=str

After:
domain.tld/?p=1234 → domain.tld/custom/permalink/
domain.tld/?id=8&p=1234&str=str → domain.tld/custom/permalink/?id=8&str=str

// Append any query compenent
    $append_query = preg_replace( '/(\??)(p=\d+&?)/', '$1', strstr( $_SERVER['REQUEST_URI'], "?" ) );
    $url .= preg_replace( '/[\?&]$/', '', $append_query );

    wp_redirect( home_url()."/".$url, 301 );
