I have four arrays $V1, $V2, $V3, $V4 and for this I did the following code but the data are not inserted:
$max_count = max(array(count($_POST['kw_coukw']), count($_POST['combin_kws']), count($_POST['combined_kws']), count($_POST['combine_kws_city'])));
for($cat1 = 0; $cat1 < $max_count; $cat1++) {
    if($cat1 <= count($_POST['kw_coukw'])){
        $V1 = $_POST['kw_coukw'][$cat1];
    }else{ 
        $V1 = 0; 
    }
    if($cat1 <= count($_POST['combin_kws'])){
        $V2 = $_POST['combin_kws'][$cat1];
    }else{ 
        $V2 = 0; 
    }
    if($cat1 <= count($_POST['combined_kws'])){
        $V3 = $_POST['combined_kws'][$cat1];
    }else{ 
        $V3 = 0; 
    }
    if($cat1 <= count($_POST['combine_kws_city'])){
        $V4 = $_POST['combine_kws_city'][$cat1];
    }else{ 
        $V4 = 0; 
    }
    $qry = "INSERT INTO seo_sentence_rl_pg_create_kw (seo_sent_pg_cre_id,kw_1_id,kw_124_id,kw_1234_id,kw_1234_city_id,customized_keyword,customized_title,description) VALUES ('".$_POST['pagenm']."','".$V1."','".$V2."','".$V3."','".$V4."','".$_POST['cuskeyword']."','".$_POST['custitle']."','".$_POST['description']."')";
}
