<code><?php $con = mysql_connect("localhost:3306","root","123456") or die("数据库连接失败".mysql_error()); mysql_select_db("vote",$con) or die ("数据库选择失败".mysql_error()); mysql_query("set names utf8"); $a = mysql_query("select news from news"); $b = mysql_fetch_row($a); while($b = mysql_fetch_row($a)) { echo $b["0"].'<br>'; echo $b["1"].'<br>'; }?></code>为什么下面会报错？？
<code>Notice: Undefined offset: 1 in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\project\brief.php on line 25Do you think it will Notice: Undefined offset: 1 in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\project\brief.php on line 25Do you think itNotice: Undefined offset: 1 in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\project\brief.php on line 25</code>
