Looping through character data and items from MySQL DB in PHP -

-

i have following code: 

include "config.php"; error_reporting(0);  $idsuccess = 0;  if(isset($_post['username'])) {      $usr = $_post['username'];     $pwd = $_post['userpwd'];     $sqlq = "select * dr_users dr_user_name='$usr' , dr_user_pwd='$pwd' limit 1";     $q = mysql_query($sqlq);      if(mysql_num_rows($q) > 0)     {          $usero = mysql_fetch_assoc($q);         $userdata = array('userid' => $usero['dr_user_id'], 'username' => $usero['dr_user_name'], 'userpwd' => $usero['dr_user_pwd'], 'usereml' => $usero['dr_user_email'], 'privlvl' => $usero['dr_user_priv_level']);         $idsuccess = 1;         $uid = $usero['dr_user_id'];         $charq = mysql_query("select * dr_chars dr_user_id='$uid'");          while($char = mysql_fetch_array($charq))         {              $chars[] = $char;             $charid = $char['dr_char_id'];             $itemq = mysql_query("select * dr_items dr_char_id='$charid'");              while($item = mysql_fetch_array($itemq))             {                  $itemdata[] = array('itemid' => $item['dr_item_id'], 'itemname' => $item['dr_item_name'], 'itemdesc' => $item['dr_item_desc'], 'itemtype' => $item['dr_item_type'], 'itemcost' => $item['dr_item_cost'], 'itemcurtype' => $item['dr_item_cur_type'], 'itematk' => $item['dr_item_stat_atk'], 'itemdef' => $item['dr_item_stat_def'], 'itemend' => $item['dr_item_stat_end'], 'itemluck' => $item['dr_item_stat_luck'], 'itemfileurl' => $item['dr_item_file_url'], 'itemstaff' => $item['dr_item_staff'], 'itemequipped' => $item['dr_char_eqp'], 'spx' => $item['dr_static_pos_x'], 'spy' => $item['dr_static_pos_y']);                              }              $chardata[] = array('charid' => $char['dr_char_id'], 'charname' => $char['dr_char_name'], 'charrace' => $char['dr_char_race'], 'charlvl' => $char['dr_char_lvl'], 'charitems' => $itemdata);          }          $resdata = array('idsuccess' => $idsuccess, 'user' => $userdata, 'chars' => $chardata);      } else {       $resdata = array('idsuccess' => $idsuccess);      }      echo json_encode($resdata);  }  ?>

i have loaded character data table 'dr_chars' in database. i'm trying load corresponding item data retrieved character id , push $chardata array. can encode & output in json format.

if question isn't clear ask , i'll try explain situation better. json data being outputted flash dynamic use.

i managed fix final code follows:

<?php  include "config.php"; error_reporting(0);  $idsuccess = 0;  if(isset($_post['username'])) {      $usr = $_post['username'];     $pwd = $_post['userpwd'];     $sqlq = "select * dr_users dr_user_name='$usr' , dr_user_pwd='$pwd' limit 1";     $q = mysql_query($sqlq);      if(mysql_num_rows($q) > 0)     {          $usero = mysql_fetch_assoc($q);         $userdata = array('userid' => $usero['dr_user_id'], 'username' => $usero['dr_user_name'], 'userpwd' => $usero['dr_user_pwd'], 'usereml' => $usero['dr_user_email'], 'privlvl' => $usero['dr_user_priv_level']);         $idsuccess = 1;         $uid = $usero['dr_user_id'];         $charq = mysql_query("select * dr_chars dr_user_id='$uid'");         $chars = array();          while($char = mysql_fetch_array($charq))         {               $charid = $char['dr_char_id'];             $itemq = mysql_query("select * dr_items dr_char_id='$charid'");             $items = array();              while($item = mysql_fetch_array($itemq))             {                  $items[] = array('itemid' => $item['dr_item_id'], 'itemname' => $item['dr_item_name'], 'itemdesc' => $item['dr_item_desc'], 'itemtype' => $item['dr_item_type'], 'itemcost' => $item['dr_item_cost'], 'itemcurtype' => $item['dr_item_cur_type'], 'itematk' => $item['dr_item_stat_atk'], 'itemdef' => $item['dr_item_stat_def'], 'itemend' => $item['dr_item_stat_end'], 'itemluck' => $item['dr_item_stat_luck'], 'itemfileurl' => $item['dr_item_file_url'], 'itemstaff' => $item['dr_item_staff'], 'itemequipped' => $item['dr_char_eqp'], 'spx' => $item['dr_static_pos_x'], 'spy' => $item['dr_static_pos_y']);              }              $chars[] = array('charid' => $char['dr_char_id'], 'charname' => $char['dr_char_name'], 'charrace' => $char['dr_char_race'], 'charlvl' => $char['dr_char_lvl'], 'charitems' => $items);          }          $resdata = array('idsuccess' => $idsuccess, 'user' => $userdata, 'chars' => $chars);      } else {       $resdata = array('idsuccess' => $idsuccess);      }      echo json_encode($resdata);  }  ?>
