开始：使用Medoo是非常简单的事!

Medoo1.2开始不支持PHP5.4或以下,若你使用的是1.2以前的版本,请选择菜单 中文文档(<1.2)

要求：

1、PHP>=5.4, 必须支持PDO

2、支持 MySQL, MSSQL, SQLite 等数据库.

3、确保php_pdo_xxx (xxx = 数据库类型) 的xxx数据扩展已经正确安装并启用.

4、需要懂一些SQL知识.

PHP PDO扩展列表

MySQL, MariaDB -> php_pdo_mysql

MSSQL (Windows) -> php_pdo_sqlsrv

MSSQL (Liunx/UNIX) -> php_pdo_dblib / php_pdo_sqlsrv

Oracle -> php_pdo_oci

Oracle version 8 -> php_pdo_oci8

SQLite -> php_pdo_sqlite

PostgreSQL -> php_pdo_pgsql

Sybase -> php_pdo_dblib

PHP PDO安装

medoo需要PHP支持PDO扩展，请在安装相关扩展后继续以下操作

打开php.ini找到你想要的相应扩展,去掉前面的;号即可

将：

;extension=php_pdo_mysql.dll

修改成：

extension=php_pdo_mysql.dll

保存，重启你的PHP或者服务器

如果PDO安装成功，你可以通过phpinfo()查看到它.

如果你通过终端(linux)命令行安装，系统会自动安装配置相应扩展

$ sudo apt-get install php5-mysql

使用 PHP Composer 安装

如果你通过php自带的依赖扩展安装它，可以使用下面的命令，或者你根据自己的需要修改即可。

$ composer require catfan/Medoo

源文件安装

这是最简单的方法，下载medoo源文件，放到你的PHP开发目录里，载入即可

require 'medoo.php';

Medoo配置

这儿提供三种数据库的连接演示.

1. // If you installed via composer, just use this code to requrie autoloader on the top of your projects.
2. require 'vendor/autoload.php';
3. // Using Medoo namespace
4. use Medoo\Medoo;
5. $database = new Medoo([
6. // required
7. 'database_type' => 'mysql',
8. 'database_name' => 'name',
9. 'server' => 'localhost',
10. 'username' => 'your_username',
11. 'password' => 'your_password',
12. // [optional]
13. 'charset' => 'utf8',
14. 'port' => 3306,
15. // [optional] Table prefix
16. 'prefix' => 'PREFIX_',
17. // [optional] Enable logging (Logging is disabled by default for better performance)
18. 'logging' => true,
19. // [optional] MySQL socket (shouldn't be used with server and port)
20. 'socket' => '/tmp/mysql.sock',
21. // [optional] driver_option for connection, read more from http://www.php.net/manual/en/pdo.setattribute.php
22. 'option' => [
23. PDO::ATTR_CASE => PDO::CASE_NATURAL
24. ],
25. // [optional] Medoo will execute those commands after connected to the database for initialization
26. 'command' => [
27. 'SET SQL_MODE=ANSI_QUOTES'
28. ]
29. ]);
30. $database->insert("account", [
31. "user_name" => "foo",
32. "email" => "foo@bar.com"
33. ]);

定制DSN链接

缺省情况下Medoo不支持的数据库您还可以使用自定义DSN连接，特别是一些新数据库,DSN参数比较特殊，或者如果要为连接添加更多的DSN参数值。

连接格式.

{driver}:{key}={value};{key}={value}

1. $database = new Medoo([
2. // Started using customized DSN connection
3. 'dsn' => [
4. // The PDO driver name for DSN driver parameter
5. 'driver' => 'mydb',
6. // The parameters with key and value for DSN
7. 'server' => '12.23.34.45',
8. 'port' => '8886'
9. ],
10. // [optional] Medoo will have different handle method according to different database type
11. 'database_type' => 'mysql',
12. 'username' => 'your_username',
13. 'password' => 'your_password'
14. ]);
15. // The final DSN connection string will be generated like this
16. mydb:server=12.23.34.45;port=8886

连接 SQLite

如果你要使用Medoo连接你的MSSQL数据库，你需要安装相关扩展：Windows安装pdo_sqlsrv、Linux/UNIX安装pdo_dblib. pdo_mssql 扩展已被PHP废弃，不建议使用.

1. $database = new Medoo([
2. 'database_type' => 'mysql',
3. 'database_name' => 'name',
4. 'server' => 'localhost',
5. 'username' => 'your_username',
6. 'password' => 'your_password',
7. // [optional] The application name
8. 'appname' => 'test',
9. // [optional] If you want to force Medoo to use dblib driver for connecting MSSQL database
10. 'driver' => 'dblib'
11. ]);

现在Medoo可以使用sqlsrv来驱动MSSQL，详见微软官方文档 https://docs.microsoft.com/en-us/sql/connect/php/connection-options?view=sql-server-2017.

1. $database = new Medoo([
2. 'database_type' => 'mysql',
3. 'database_name' => 'name',
4. 'server' => 'localhost',
5. 'username' => 'your_username',
6. 'password' => 'your_password',
7. // [optional] MSSQL connection options
8. 'application_intent' => 'ReadOnly',
9. 'attach_db_file_name' => './database.sql',
10. 'authentication' => 'SqlPassword',
11. 'column_encryption' => 'Enabled',
12. 'connection_pooling' => 1,
13. 'encrypt' => 1,
14. 'failover_partner' => 'MultiSubnetFailover',
15. 'key_store_authentication' => 'KeyVaultPassword',
16. 'key_store_principal_id' => 'AzureName',
17. 'key_store_secret' => 'AzurePass',
18. 'login_timeout' => '20',
19. 'multiple_active_result_sets' => 1,
20. 'multi_subnet_failover' => 'Yes',
21. 'scrollable' => 'buffered',
22. 'trace_file' => './path',
23. 'trace_on' => 1,
24. 'transaction_isolation' => PDO::SQLSRV_TXN_SNAPSHOT,
25. 'transparent_network_ip_resolution' => 'Enabled',
26. 'trust_server_certificate' => 1,
27. 'wsid' => 'Computer1'
28. ]);

连接 SQLite

1. $database = new medoo([
2. 'database_type' => 'sqlite',
3. 'database_file' => 'my/database/path/database.db'
4. ]);
5. $database->insert("account", [
6. "user_name" => "foo",
7. "email" => "foo@bar.com"
8. ]);
