代码[mw_shl_code=php,true]<?php
function get_td_array($table) {

      //去掉空白字符

            array_pop($td);
            $td_array[] = $td;
      }
      return $td_array;
}

  $s=file_get_contents('http://chengji.lideping.com:7000/exam/query/query.jsp?logname=20133011235');
  $s=mb_convert_encoding("$s", "UTF-8", "GBK");  //编码转换
  //获取最后一个table内容
  $s=substr($s,strrpos($s,'<table'));
  $s=substr($s,0,strpos($s,'</table>')+8);
  //删除超链接
  $s=preg_replace('|<a href.*?</a>|','',$s);
$s=preg_replace('|<td align=\'center\'></td>|','',$s);//删除多余空格

  echo $s;
  preg_match_all('/<table [^>]*>([\s\S]*?)<\/table>/',$s,$table);//用正则表达式将课表的表格取出
  $arr = get_td_array($table[0][0]);//执行函数
  print_r($arr);
?>
[/mw_shl_code] 函数是将表格转换为数组的函数，网上找的。。问题是：

一样的代码，上面的这个就输出了完全的数组

已调整完全正确输出，给楼主你注释了哪句代码的问题
