如何使用php+mysql在两个数据库之间复制表？

有时我想在两个表之间直接使用php复制表，这对我来说似乎太难了。有谁知道怎么做吗？请参阅下面的我的代码:

<?php 

// database: a   ,  table: user
name | age | sex
jimmy | 30 | male
ricky | 20 | male
tina | 20 | female

// database: b   ,  table: user
name | age
kelvin | 30

// I want to copy a.user to replace b.user completely, how to do it in php+mysql?
$db_a = $db->connect($a_config);
$db_b = $db->connect($b_config);
// $db_a->table('user')->copy_to($db_b); // only explaining what I want to do

// final result: b.user is
name | age | sex
jimmy | 30 | male
ricky | 20 | male
tina | 20 | female

Answer 1

create table db_a.table_name like db_b.table_name;

创建表后，您必须像这样插入数据

insert into db_b.table_name select * from db_a.table_name;
