My php code is as:

<?php
    if($_POST){
        foreach ($_POST['IdRelInto'] as $idx1 => $value1) {
            foreach ($_POST['IdRelTo'] as $idx => $value) {
                $DateArray[] = array(
                    'checkboxDA'  => $_POST['checkboxDA'][$idx],
                    'prts'        => $_POST['prts'][$idx],
                    'IdRelInto'   => $_POST['IdRelInto'][$idx],
                    'IdRelTo'     => $_POST['IdRelTo'][$idx]
                    );
            };
        };
                echo '<pre>';
                print_r($DateArray);
    //$this->db->insert_batch('hoPV', $DateArray); This is for CodeIgniter
    }
?>
