Answer 1

Something like this

function ownMin($value)
    {
    return min(array_filter(func_get_args()));
    }
$a = 0; $b = 3; $c= 4; $d = 8;
echo ownMin($a,$b,$c,$d); // 3

Answer 2

Try this:

function my_min(){
   $excludes = array(0); // anything, that should be filtered out.
   $values   = array_diff(func_get_args(), $excludes);

   return min($values);
}

var_dump(my_min(12, 0, 15, 0, 18));

Shows:

int(12)

Take a look at array_diff() and func_get_args().
