I  need a function that:

Checks to see if every value is the same. (excluding 0's( eg. 1,1,1,0 are the same.))-> Returns the "same value" (eg. 1)
Else outputs false

Thanks.

Sorry, args:
($array) (Type is Array)
This should work:

function allSame($arr)
{
   $s = 5972383346264832; //a random number that will not be in the array by chance
   foreach ($arr as $value)
   {
      if ($value != 0)
      {
         if ($s == 5972383346264832)
        {
            $s = $value;
        }
        else
        {
           if ($s != $value)
           {
              return FALSE;
           }
        }
      }
   }
   return $s;
}

You can use any of the Array function the PHP provides like:
array_diff, array_intersect, array_search, array_unique, in_array
