求教一个php调用数据库输出的问题
目的是做一个 选择范围然后 通过这些范围查询数据库并格式化输出结果的

但是做到输出就出问题了 弄了半天很不理解
以下是错误部分代码

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->mysql_query('set names gbk',$conn);mysql_select_db('htc',$conn);$count = 'select count(*) from phone';$query = mysql_query($count,$conn);//记录总数$recordcount = mysql_result($query, 0,0);//每页多条$pagesize = 5;//总页数$pagecount = ceil($recordcount/$pagesize);//当前页$currpage = 1;if($_GET){    $currpage = (int)$_GET['p'];    }    $currpage = $currpage$pagecount ? $pagecount : $currpage;                        $start = ($currpage-1)*$pagesize;    $sql = "select * from phone order by id desc limit $start,$pagesize";    $result = mysql_query($sql,$conn);    while($row=mysql_fetch_array($result)){    foreach ($row as $k=>$va){    //echo '<pre class="brush:php;toolbar:false">';    //print_r($row);                                echo "<div class="p_list">";    echo "<div class="p_list_pic"><a><img  src="." alt="求教一个php调用数据库输出的有关问题" >"."</a></div>";    echo "<div class="p_list_con">        <p class="p_list_con_title">$va[1]</p>
<br>            $va[4],$va[5]<br>            $va[6],$va[7]<br>            $va[8],$va[9]<br>              <p class="p_list_con_state">$va[10]</p>
</div>";            echo "<div>售价:¥$va[3]<br>            <img  src="image/gm.gif" alt="求教一个php调用数据库输出的有关问题" >
</div>";            echo "</div>";            //echo '
'; } } echo '首页 '; echo '下页 '; echo '上页 '; echo "末页  "; echo "[{$currpage}/{$pagecount}][共{$recordcount}记录,每页{$pagesize}条]"; ?>

错误提示是很多行  
但基本上都是提示说


Notice: Uninitialized string offset: 6 in D:\Program Files\Apache\htdocs\pro\phone_zone.php on line 183

Notice: Uninitialized string offset: 7 in D:\Program Files\Apache\htdocs\pro\phone_zone.php on line 183

求教

------解决方案--------------------
while($row=mysql_fetch_array($result)){//mysql_fetch_array($result)返回的是一维数组
foreach ($row as $k=>$va){//所以$va是单值数据
//echo '
';<br>   //print_r($row);<br>                          <br>   echo "<div class="p_list">";<br>   echo "<div class="p_list_pic"><a><img  src="." alt="求教一个php调用数据库输出的有关问题" >"."</a></div>";<br>   echo "<div class="p_list_con">
<br>       <p class="p_list_con_title">$va[1]</p>
<br><br>           $va[4],$va[5]<br><br>           $va[6],$va[7]<br>//所以$va[6],$va[7]只能是单个字符,如果$val没有那么长,则就要报错了<br><br>我认为你的本意应该是<br><br>   while($val=mysql_fetch_array($result)){<br>   //foreach ($row as $k=>$va){<br><br>也就是说:$va[6],$va[7]是第6,7个字段的值<br><font color="#e78608">------解决方案--------------------</font><br>去掉foreach那层循环。<br>while($va = mysql_fetch_row($result) ){<br>// ...<br>}<br><br>至于你#2说的问题,我不会正则表达式所以帮不上忙<br><font color="#e78608">------解决方案--------------------<div class="clear">
