We often encounter the problem of replacing or adding the database table prefix. This is also a method, but it is not convenient enough. You can export the database, change it in batches in notepad, and then export it again.

The following method makes it easy to solve the problem. The Code is as follows.

　　

$ Database = "databaseName ";

// Database Name

$ User = "root ";

// Database username

$ Pwd = "pwd ";

// Database Password

$ Replace = 'pre _';

// The prefix after replacement

$ Seach = 'pre1 _';

// The prefix to be replaced

$ Db = mysql_connect ("localhost", "$ user", "$ pwd") or die ("Database Connection Failed:". mysql_error ());

// Connect to the database

$ 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 ");

}

?>

If you want to add a prefix, you only need to change it a little bit.

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

Change to $ table = $ replace. $ name ['0'];

You can.
