用mysql扩展类把数据库数据取出放在表格上

<?php 
    header("Content-Type:text/html;charset=utf-8");
    function OtherFunction($dbnamem,$tbname){
        $conn = mysql_connect('localhost','root','') or die(mysql_error());
        mysql_query("use ".$dbnamem) or die(mysql_error());
        mysql_query("set names utf8") or die(mysql_error());
        $sql = "select * from ".$tbname;
        $res = mysql_query($sql) or die(mysql_error());
        //取得行数
        // $rows = mysql_affected_rows($conn);
        // $rows = mysql_num_rows($res);
        $colums = mysql_num_fields($res);
        //取出表头
        echo "<table border=1><tr>";
        for ($i=0; $i < $colums; $i++) { 
            # code...
            $file_name = mysql_field_name($res, $i);
            echo "<th>$file_name</th>";
        }
        echo "</tr>";

        // echo "<tr>";
        //取出行信息
        while ($row = mysql_fetch_row($res)) {
            # code...
            echo "<tr>";    //    循环输出行
            for ($i=0; $i < $colums; $i++) { 
                # code...
                echo "<td>$row[$i]</td>";    //循环输出列
            }
            echo "</tr>";
        }
        // echo "</tr>";

        echo "</table>";

    }
    $dbnamem = "mysql";
    $tbname = "user";
    OtherFunction($dbnamem,$tbname);

 ?>
