$PHP_SELF / Form / Array / Static Variable

[universelittle]

1. Why the size of array is always 1? What's wrong?
2. How to hide the form after submit while call itself? I tested, my code doesn't work, so i comment it.
   Many thanks!!!

<?  $dbhost = "localhost";
    $dbuser = "admin";
    $dbpass = "pass";
    $dbname = "webDB";
    $connect = mysql_connect($dbhost,$dbuser,$dbpass)or die ("Could not connect to database");
    mysql_select_db($dbname,$connect)or die ("Could not select database");
    static $i;

if (isset($_POST['addstock'])){
             echo ("symbol: ".$_POST['symbol']);
             $query = mysql_query("SELECT * FROM stocks WHERE symbol='".$_POST['symbol']."'",$connect);
             if (!$rec = mysql_fetch_array($query)){
                echo("Sorry, no such symbol found!");
             }
             else {
                $mystocks[$i]=$_POST['symbol'];
                $i++;
             }

         /*echo("<form>
               <input type=\"hidden\" name=\"symbol\" value=\"$symbol\">
               <input type=\"hidden\" name=\"addstock\">
               <input type=\"hidden\" name=\"removestock\">
               </form>"); */
}
echo("<BR>size of mystocks is: ".sizeof($mystocks));

if (sizeof($mystocks)!=0){
   foreach ($mystocks as $mysymbol){
      $query = mysql_query("SELECT * FROM stocks WHERE symbol='".$mysymbol."'",$connect);
      while ($rec = mysql_fetch_array($query)){
         echo("<BR>Symbol: ".$rec["symbol"]." Company: ".$rec["company"]." Ask: ".$rec["ask"]);
      }
   }
}   


  echo("<form action=\"".$_SERVER['$PHP_SELF']."\" method=\"post\">
  Symbol:
  <input type=\"text\" name=\"symbol\">
  <input type=\"submit\" name=\"addstock\" value=\"Add Stock\">
  <input type=\"submit\" name=\"removestock\" value=\"Remove Stock\">
  </form>");


?>

Maybe I'm just missing something here, but I'm not entirely sure what the actual problem is...?

I think I understand question #1, but what do you mean by #2? What exactly doesn't work?
