PHP代码如下

<?php                    
                  
$user = ""; //数据库用户名                    
$password = "";//数据库密码                   
$db_name = "";//数据库名                    
                  
$link = mysql_connect("localhost:3306",$user,$password);                    
mysql_select_db("$db_name",$link);                    
echo "<p>正在清空数据库,请稍等....";                    
$result=mysql_query("SHOW tables",$link);                    
while ($currow=mysql_fetch_array($result)) {                    
mysql_query("drop TABLE IF EXISTS $currow[0]");                    
echo $currow[0]."<br>";                    
}                    
echo "恭喜你清理MYSQL成功</p>";                    
?>

下面代码保存为***.php运行就OK了

清空完就从服务器上删掉就OK了。。
