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

Question

I have the following code:
include "config.php";
error_reporting(0);
$idSuccess = 0;
if(isset($_POST['userName']))
{
$usr = $_POST['userName'];
$pwd = $_POST['userPwd'];
$sqlQ = "SELECT * FROM dr_users where dr_user_name='$usr' AND 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'];
$charQ = mysql_query("SELECT * FROM dr_chars WHERE dr_user_id='$uID'");
while($char = mysql_fetch_array($charQ))
{
$chars[] = $char;
$charID = $char['dr_char_id'];
$itemQ = mysql_query("SELECT * FROM dr_items WHERE dr_char_id='$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 successfully loaded character data from the table 'dr_chars' in my database. I'm trying to load the corresponding item data from the retrieved character ID and push it into the $charData array. So I can then easily encode & output it in a JSON format.
If my question isn't clear just ask and I'll try to explain the situation better. The JSON data is being outputted into flash for dynamic use.
I managed to fix this final code as follows:
<?php
include "config.php";
error_reporting(0);
$idSuccess = 0;
if(isset($_POST['userName']))
{
$usr = $_POST['userName'];
$pwd = $_POST['userPwd'];
$sqlQ = "SELECT * FROM dr_users where dr_user_name='$usr' AND 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'];
$charQ = mysql_query("SELECT * FROM dr_chars WHERE dr_user_id='$uID'");
$chars = array();
while($char = mysql_fetch_array($charQ))
{
$charID = $char['dr_char_id'];
$itemQ = mysql_query("SELECT * FROM dr_items WHERE dr_char_id='$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);
}
?>
