  我们经常会遇到替换或添加数据库表前缀的问题,通过数据库导出,在记事本上批量更改,然后再导出,这也是一种方法,但是不够方便。

  通过下面这个方法,轻松搞定,代码如下,有用到的顶起。

  

  $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

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

  换成   $table = $replace.$name['0'];

  就可以了。
