所以自己简单写了几行代码用来实现以上需求
执行结果： 
复制代码代码如下:
<?php
$conn=mysql_connect('localhost','root','');
mysql_select_db('数据库',$conn);
$sql="SELECT information_schema.TABLES.TABLE_NAME FROM information_schema. TABLES WHERE table_schema = '数据库'";
$res=mysql_query($sql);
while ($result = mysql_fetch_assoc($res)) {
$tables[]=$result['TABLE_NAME'];
};
echo "<table>
<tbody>
<tr>
<td>表名</td>
<td>数据量</td>
</tr>";
foreach ($tables as $k=>$v){
$sql_count="select count(id) AS nums,'".$v."' from ".$tables[$k];
$res_count=mysql_query($sql_count);
$result_count = mysql_fetch_assoc($res_count);
echo "<tr><td>".$result_count[$v].'</td><td>'.$result_count['nums'].'</td></tr>';
}
echo "</tbody></table>"
?>
