通过下面这个方法,轻松搞定,代码如下,有用到的顶起。
复制代码 代码如下:
        $database = "databaseName";         //数据库名称
        $user = "root";                       //数据库用户名
        $pwd = "pwd";                         //数据库密码
        $replace ='pre_';                     //替换后的前缀
        $seach = 'pre1_';                     //要替换的前缀
        $db=mysql_connect("localhost","$user","$pwd") or die("连接数据库失败:".mysql_error());         //连接数据库

        $tables = mysql_list_tables("$database");       
        while($name = mysql_fetch_array($tables)) {

                $table = str_replace($seach,$replace,$name['0']);

                mysql_query("rename table $name[0] to $table");
        }

?>

如果是添加前缀只需要变化一点点
复制代码 代码如下:
   $table = str_replace($seach,$replace,$name['0']);换成
   $table = $replace.$name['0'];

就可以了。
