PHP database framework Medoo1.6 installation tutorial

Start

Using Medoo is very simple!

Medoo1.2 does not support PHP5.4 or below. If you are using it before 1.2 Version, please select the menu Chinese Document (

Requirements

1, PHP>=5.4, must support PDO

2, support MySQL, MSSQL, SQLite and other databases.

3. Make sure that the xxx data extension of php_pdo_xxx (xxx = database type) has been correctly installed and enabled.

4. You need to know some SQL knowledge.

PHP PDO extension list

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 installation

medoo requires PHP to support PDO extensions, please install the relevant extensions Continue the following operations

// 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.

If you install through the terminal (linux) command line, the system will automatically install and configure the corresponding extension

$ sudo apt-get install php5-mysql

Use PHP Composer to install

If you install it through the dependency extension that comes with PHP, you can use the following command, or you can modify it according to your own needs.

$ composer require catfan/Medoo

Source file installation

This is the simplest method, download the medoo source file, put it in your PHP development directory, and load it

require  'medoo.php';

Medoo configuration

Here provides three database connection demonstrations.

// 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 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"
]);

Customized DSN link

Missing You can also use custom DSN connections for databases that Medoo does not support, especially for new databases where the DSN parameters are special, or if you want to add more DSN parameter values ​​to the connection.

Connection format.

{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 this
mydb:server=12.23.34.45;port=8886

Connect to SQLite

If you want to use Medoo to connect to your MSSQL database, you need to install the relevant extension: Windows installation pdo_sqlsrv , Linux/UNIX install pdo_dblib. The pdo_mssql extension has been abandoned by PHP and is not recommended.

$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'
]);

Now Medoo can use sqlsrv to drive MSSQL. For details, see Microsoft official documentation 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'
]);

Connect to SQLite

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