也可以用如下辦法：

保存為***.php　運行就OK了

<?php

$user = ""; //數(shù)據(jù)庫用戶名
$password = "";//數(shù)據(jù)庫密碼
$db_name = "";//數(shù)據(jù)庫名

$link = mysql_connect("localhost:3306",$user,$password);
mysql_select_db("$db_name",$link);
echo "<p>正在清空數(shù)據(jù)庫...";
$result=mysql_query("SHOW tables",$link);
while ($currow=mysql_fetch_array($result)) {
mysql_query("drop TABLE IF EXISTS $currow[0]");
echo $currow[0]."<br>";
}
echo "成功</p>";

?>
