<?
$host = "localhost";   //主机名
$user = "root";        //mysql用户名
$password = "";    //mysql密码
$database = "doc";  //mysql数据库名
$tables = "mclass";  //表名

$conn=mysql_connect("$host","$user","$password") or die("数据库打开出错");
mysql_select_db("$database");

   $query="select * from $tables";
    $result=mysql_query($query,$conn);
    $i=0;
    $j=0;
      while($row=mysql_fetch_row($result)){
      $array[$i][$j] = $row[0].$row[1];
        $array2[$i][$j] = $row[0];
     $j++; // echo $i.",".$j.$row[1]."<br>";
     if($j==3) {
     $i++;
     $j=0;
         } //else {$j++ ;}

       }
     $amax=count($array);//获是数组内数据个数。

    $rows=2;  //设置列数

   //开始显示数据
  for ($x=0; $x<=$amax-1; $x++) {
       for ($y=0; $y<= $rows; $y++) {
         echo "<a href=".$array2[$x][$y].">".$array[$x][$y]."</a>|" ;
          }
          echo "<p>";
    }

/*
显示结果为
