$_SESSION multidimensional array issues

Please i need help, this code below works fine on my localhost, php5.3+ but on the server its not working fine. 5.2

    $_SESSION['myinv_id'] = $setinvid;
    $_SESSION['prod_name'][$i] = $prod_name;    
    $_SESSION['qty'][$i] = $clean_qty;
    $_SESSION['price'][$i] = $clean_price;
    $_SESSION['total'][$i] = $clean_total;
    $_SESSION['desc'][$i] = $desc;

when i did a var_dump

The first time contents were added, i had these.

    array(5) { 
     ["prod_name"]=> array(1) {[0]=> string(4) "SDFD" }
     ["qty"]=> array(1) {[0]=> string(2) "43"} 
     ["price"]=> array(1) { [0]=> string(2) "43" } 
     ["total"]=> array(1) { [0]=> string(4) "1849" } 
     ["desc"]=> array(1) { [0]=> string(6) "dsfsdf" } }

works fine....as the array is returned but in an attempt to added a second value...i get these error...saying Fatal Error [] not expected for strings..when i did a var_dump...i had these...in these case, ['prod_name'] & ['desc'] has inevitable changed from array to string and an array value cannot be pushed into the stake.

    array(5) { 
     **["prod_name"]=> &string(5) "dddsd"** 
      ["qty"]=> &array(2) { 
        [0]=> string(2) "43" 
       [2]=> string(2) "45" }
       ["price"]=> &array(2) { 
  [0]=> string(2) "43" 
     [2]=> string(1) "3" } 
     ["total"]=> &array(2) { 
[0]=> string(4) "1849" 
        [2]=> string(3) "135" } 
      **["desc"]=> &string(7) "dsddadd"** }

Please what could be the source of the problem, and i have even tried decalaring this session variables as an empty array before using them, yet no avail.

Your question seems to be why is my session array mysteriously being modified all by itself?

If the php config has register_globals enabled, then, $var and $_SESSION['var'] become the same variable(via references). This can lead to some real code wtf's because assigning a value to $var also assigns the value to $_SESSION['var']

I can't remember, but the reference between the two variable may only be established when session_start is called. Also, I would imagine this only occurs in the global scope.
