Question

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

• PHP>=5.4, 必须支持PDO.
• 支持 MySQL, MSSQL, SQLite 等数据库.
• 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.
• 需要懂一些SQL知识.

Tips

在PHP5.4+中你可以使用[]作为数组参数语法，而不再使用array().

// On PHP 5.1var data = array("foo", "bar");// On PHP 5.4+var data = ["foo", "bar"];

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

PHP依赖安装

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

升级方法

$ composer update

安装源文件安装

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';

配置

这儿提供三种数据库的连接演示.

// If you installed via composer, just use this code to requrie autoloader on the top of your projects.require 'vendor/autoload.php';// Using Medoo namespaceuse Medoo\Medoo;$database = new Medoo([	// required	'database_type' => 'mysql',	'database_name' => 'name',	'server' => 'localhost',	'username' => 'your_username',	'password' => 'your_password',	// [optional]	'charset' => 'utf8',	'port' => 3306,	// [optional] Table prefix	'prefix' => 'PREFIX_',	// [optional] Enable logging (Logging is disabled by default for better performance)	'logging' => true,	// [optional] MySQL socket (shouldn't be used with server and port)	'socket' => '/tmp/mysql.sock',	// [optional] driver_option for connection, read more from http://www.php.net/manual/en/pdo.setattribute.php	'option' => [		PDO::ATTR_CASE => PDO::CASE_NATURAL	],	// [optional] Medoo will execute those commands after connected to the database for initialization	'command' => [		'SET SQL_MODE=ANSI_QUOTES'	]]);$database->insert("account", [	"user_name" => "foo",	"email" => "foo@bar.com"]);

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}

$database = new Medoo([	// Started using customized DSN connection	'dsn' => [		// The PDO driver name for DSN driver parameter		'driver' => 'mydb',		// The parameters with key and value for DSN		'server' => '12.23.34.45',		'port' => '8886'	],	// [optional] Medoo will have different handle method according to different database type	'database_type' => 'mysql',	'username' => 'your_username',	'password' => 'your_password']);// The final DSN connection string will be generated like thismydb:server=12.23.34.45;port=8886    

For MSSQL

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.

$database = new Medoo([	'database_type' => 'mysql',	'database_name' => 'name',	'server' => 'localhost',	'username' => 'your_username',	'password' => 'your_password', 	// [optional] The application name	'appname' => 'test', 	// [optional] If you want to force Medoo to use dblib driver for connecting MSSQL database	'driver' => 'dblib']);

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.

$database = new Medoo([	'database_type' => 'mysql',	'database_name' => 'name',	'server' => 'localhost',	'username' => 'your_username',	'password' => 'your_password', 	// [optional] MSSQL connection options	'application_intent' => 'ReadOnly',	'attach_db_file_name' => './database.sql',	'authentication' => 'SqlPassword',	'column_encryption' => 'Enabled',	'connection_pooling' => 1,	'encrypt' => 1,	'failover_partner' => 'MultiSubnetFailover',	'key_store_authentication' => 'KeyVaultPassword',	'key_store_principal_id' => 'AzureName',	'key_store_secret' => 'AzurePass',	'login_timeout' => '20',	'multiple_active_result_sets' => 1,	'multi_subnet_failover' => 'Yes',	'scrollable' => 'buffered',	'trace_file' => './path',	'trace_on' => 1,	'transaction_isolation' => PDO::SQLSRV_TXN_SNAPSHOT,	'transparent_network_ip_resolution' => 'Enabled',	'trust_server_certificate' => 1,	'wsid' => 'Computer1']);

For SQLite

$database = new medoo([    'database_type' => 'sqlite',    'database_file' => 'my/database/path/database.db']);$database->insert("account", [    "user_name" => "foo",    "email" => "foo@bar.com"]);
