check if function returns something

If the function validateCustomForm() returns nothing, then that means all of the variables are set. I tried using empty() but I figured since there is something in the function that it will always return false.

How can I check if a function returns something?

Script in action here

<?php

function validateCustomForm(){

$os0 = "";
$os1 = "5";
$os2 = "6";
$os3 = "5";
    if(!empty($os0)){
    //do nothing
    }else{
            $w = "width is missing";
    echo $w;
    }
    if(!empty($os1)){
    //do nothing
    }else{
            $h = "height is missing";
    echo $h;
    }
    if(!empty($os2)){
    //do nothing
    }else{
            $c = "color is missing";
    echo $c;
    }
    if(!empty($os3)){
    //do nothing
    }else{
            $q = "qty is missing";
    echo $q;
    }

    }//end function

$valid = validateCustomForm();

if(!empty($valid)){
echo "something is missing";
} else{
echo "all good";
}
