如何在PHP項目中使用phinx進行數據遷移和建表

建表

phinx\bin\phinx.bat migrate -e production

建設 phinx.yml文件

paths:

migrations: %%PHINX_CONFIG_DIR%%\database\migrations

seeds: %%PHINX_CONFIG_DIR%%\database\seeds

environments:

default_migration_table: phinxlog

default_database: development

production:

adapter: mysql

host: localhost

name: jitamin2

user: root

pass: ‘‘

port: 3306

charset: utf8

development:

adapter: mysql

host: localhost

name: development_db

user: root

pass: ‘‘

port: 3306

charset: utf8

testing:

adapter: mysql

host: localhost

name: testing_db

user: root

pass: ‘‘

port: 3306

charset: utf8

數據遷移命令如下：

phinx\bin\phinx.bat seed:run -e production

%%PHINX_CONFIG_DIR%%\database\seeds下面的文件示例CreateGroupsTable.php如下：

?php

/*

* This file is part of Jitamin.

*

* Copyright (C) Jitamin Team

*

* For the full copyright and license information, please view the LICENSE

* file that was distributed with this source code.

*/

use Jitamin\Foundation\Security\Role;

use Phinx\Seed\AbstractSeed;

class UserSeeder extends AbstractSeed

{

/**

* Run Method.

*/

public function run()

{

$data = [

[

‘username‘ = ‘admin‘,

‘password‘ = bcrypt(‘admin‘),

‘email‘ = ‘admin@admin.com‘,

‘role‘ = Role::APP_ADMIN,

],

];

$users = $this-table(‘users‘);

$users-insert($data)

-save();

}

}

php數據庫如何轉移？

把A中的q1倒出來 mysqldump -uadmin1 -padmin111 Q1 Q1.sql

然後再B中新建Q2，create database Q2

應用Q2 use Q2

導入Q1 source Q1.sql

賦予用戶 grant all privileges on Q2.* to ‘admin2’@localhost identified by ‘admin2222’

這樣就可以了！

php實現redis數據庫指定庫號遷移的方法

這篇文章主要介紹了php實現redis數據庫指定庫號遷移的方法,涉及對於redis數據庫的操作技巧,非常具有實用價值,需要的朋友可以參考下

本文實例講述了php實現redis數據庫指定庫號遷移的方法,分享給大家供大家參考。具體如下：

redis普通的數據庫遷移,只能整個redis

save,或者利用主從,當然也可以安裝一個redis-dump,不過比較麻煩,這裡提供一種php的腳本,實現指定庫號的遷移,其實也就是遍歷根據存儲類型,讀出來,插入新庫,效果是這樣:

代碼如下:

[root@localhost

~]#

php

1.php

1/407

101/407

201/407

301/407

401/407

PHP實例代碼如下:

代碼如下:

?php

$from

=

‘10.0.2.52:6379/7’;

$to

=

‘127.0.0.1:6379/7’;

$from_redis

=

redis_init($from);

$to_redis

=

redis_init($to);

$keys

=

$from_redis-keys(‘*’);

$count

=

0;

$total

=

count($keys);

foreach($keys

as

$key){

if(++$count

%

100

==

1){

echo

“$count/$totaln”;

}

$type

=

$from_redis-type($key);

switch($type){

case

Redis::REDIS_STRING:

$val

=

$from_redis-get($key);

$to_redis-set($key,

$val);

break;

case

Redis::REDIS_LIST:

$list

=

$from_redis-lRange($key,

0,

-1);

foreach($list

as

$val){

$to_redis-rPush($key,

$val);

}

break;

case

Redis::REDIS_HASH:

$hash

=

$from_redis-hGetAll($key);

$to_redis-hMSet($key,

$hash);

break;

case

Redis::REDIS_ZSET:

$zset

=

$from_redis-zRange($key,

0,

-1,

true);

foreach($zset

as

$val=$score){

$to_redis-zAdd($key,

$score,

$val);

}

break;

}

}

function

redis_init($conf){

$redis

=

new

Redis();

preg_match(‘/^([^:]+)(:[0-9]+)?/(.+)?/’,

$conf,

$ms);

$host

=

$ms[1];

$port

=

trim($ms[2],

‘:’);

$db

=

$ms[3];

$redis-connect($host,

$port);

$redis-select($db);

return

$redis;

}

?
