如何在PHP中缩短多个isset函数

Question

Look at my script:

if((isset($_POST['unma']) && isset($_POST['livi'])) && (isset($_POST['cont']) && 

    isset($_POST['phone']))){
        if(
            (
                (
                    (
                        (isset($_POST['fnma']) && isset($_POST['lnma']))
                        &&
                        (isset($_POST['occ']) && isset($_POST['hom']))
                    )
                    &&
                    (
                        (isset($_POST['town']) && isset($_POST['dist']))
                        &&
                        (isset($_POST['dispmb']) && isset($_POST['fbc']))
                    )
                )
                &&
                (
                    (
                        (isset($_POST['gp']) && isset($_POST['twt']))
                        &&
                        (isset($_POST['ins']) && isset($_POST['flc']))
                    )
                    &&
                    (
                        (isset($_POST['ile']) && isset($_POST['cam']))
                        &&
                        (isset($_POST['cam_co']) && isset($_POST['prof_phr']))
                    )
                )
            )
            &&
            isset($_POST['awards'])
        ){
                // Codes here
        }

How can I short this isset functions. I found an solution with foreach but they are not checking the post isset, rather they are checking if the posted values are not empty

You can use

if (isset($_POST['a'], $_POST['b'], $_POST['c'], ...))

and so on. If any of the variables is not set then you will get false.
