Flash数据库操作失败

Question

我的Flash（.fla）项目存在问题。我用flash脚本连接了我的flash和数据库。我使用的是ActionScript 2.0。

问题是数据可以在AdobeFlash CS6上的编译程序中显示（CTRL + Enter）但是当我打开.swf时数据不能显示在数据网格中。

这是我的PHP脚本

<?php

mysql_pconnect ("localhost", "root", "");
mysql_select_db ("modul");


   $qr = mysql_query("SELECT * from nilaisiswa");
   if (!qr || mysql_num_rows($qr)==0) {
      $r_string = '&errorcode=3&msg='.mysql_error().'&';
   } else {
      $r_string = '&errorcode=0&n='.mysql_num_rows ($qr);
      $i = 0;
      while ($row = mysql_fetch_assoc ($qr)) {
         while (list ($key, $val) = each ($row)) {
            $r_string .= '&' . $key . $i . '=' . stripslashes($val);
         }
         $i++;
      }

      $r_string .='&';
   }

echo $r_string;
?>

这是我的ActionScript 2.0
