設定
illuminate/database 支援的資料庫及版本如下:
- MySQL 5.6+
- PostgreSQL 9.4+
- SQLite 3.8.8+
- SQL Server 2017+
資料庫設定檔位於 config/database.php
。
return [
// 預設資料庫
'default' => 'mysql',
// 各種資料庫設定
'connections' => [
'mysql' => [
'driver' => 'mysql',
'host' => '127.0.0.1',
'port' => 3306,
'database' => 'webman',
'username' => 'webman',
'password' => '',
'unix_socket' => '',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
'sqlite' => [
'driver' => 'sqlite',
'database' => '',
'prefix' => '',
],
'pgsql' => [
'driver' => 'pgsql',
'host' => '127.0.0.1',
'port' => 5432,
'database' => 'webman',
'username' => 'webman',
'password' => '',
'charset' => 'utf8',
'prefix' => '',
'schema' => 'public',
'sslmode' => 'prefer',
],
'sqlsrv' => [
'driver' => 'sqlsrv',
'host' => 'localhost',
'port' => 1433,
'database' => 'webman',
'username' => 'webman',
'password' => '',
'charset' => 'utf8',
'prefix' => '',
],
],
];
使用多個資料庫
透過 Db::connection('設定名')
選擇要使用的資料庫,其中 設定名
為配置文件 config/database.php
中對應設定的 key
。
舉例來說,以下是資料庫設定:
return [
// 預設資料庫
'default' => 'mysql',
// 各種資料庫設定
'connections' => [
'mysql' => [
'driver' => 'mysql',
'host' => '127.0.0.1',
'port' => 3306,
'database' => 'webman',
'username' => 'webman',
'password' => '',
'unix_socket' => '',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
'mysql2' => [
'driver' => 'mysql',
'host' => '127.0.0.1',
'port' => 3306,
'database' => 'webman2',
'username' => 'webman2',
'password' => '',
'unix_socket' => '',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
'pgsql' => [
'driver' => 'pgsql',
'host' => '127.0.0.1',
'port' => 5432,
'database' => 'webman',
'username' => 'webman',
'password' => '',
'charset' => 'utf8',
'prefix' => '',
'schema' => 'public',
'sslmode' => 'prefer',
],
];
像這樣切換資料庫。
// 使用預設資料庫,等同於 Db::connection('mysql')->table('users')->where('name', 'John')->first();
$users = Db::table('users')->where('name', 'John')->first();;
// 使用mysql2
$users = Db::connection('mysql2')->table('users')->where('name', 'John')->first();
// 使用pgsql
$users = Db::connection('pgsql')->table('users')->where('name', 'John')->first();
