PHP数据库框架Medoo1.6安装教程

Posted 2021-02-20 ipengrui2

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

1 2 3 4 5 6 7

// 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

1	$ 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。

1	$ 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

1	require  ‘medoo.php‘;

Medoo配置

这儿提供三种数据库的连接演示.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42

// If you installed via composer, just use this code to requrie autoloader on the top of your projects. require ‘vendor/autoload.php‘;    // Using Medoo namespace use MedooMedoo;    $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" => "[e-mail]" ]);

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.

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

$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 this 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 2 3 4 5 6 7 8 9 10 11 12 13

$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.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

$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‘ ]);

连接 SQLite

1 2 3 4 5 6 7 8 9

$database = new medoo([     ‘database_type‘ => ‘sqlite‘,     ‘database_file‘ => ‘my/database/path/database.db‘ ]);    $database->insert("account", [     "user_name" => "foo",     "email" => "[e-mail]" ]);
