配置

illuminate/database 數(shù)據(jù)庫(kù)及版本支持情況如下：

• MySQL 5.6+
• PostgreSQL 9.4+
• SQLite 3.8.8+

• SQL Server 2017+

  數(shù)據(jù)庫(kù)配置文件位置為 config/database.php。

  return [
   // 默認(rèn)數(shù)據(jù)庫(kù)
   'default' => 'mysql',
   // 各種數(shù)據(jù)庫(kù)配置
   '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(gè)數(shù)據(jù)庫(kù)

  通過(guò)Db::connection('配置名')來(lái)選擇使用哪個(gè)數(shù)據(jù)庫(kù)，其中配置名為配置文件config/database.php中的對(duì)應(yīng)配置的key。

  例如如下數(shù)據(jù)庫(kù)配置：

 return [
     // 默認(rèn)數(shù)據(jù)庫(kù)
     'default' => 'mysql',
     // 各種數(shù)據(jù)庫(kù)配置
     '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',
          ],
 ];

像這樣切換數(shù)據(jù)庫(kù)。

// 使用默認(rèn)數(shù)據(jù)庫(kù)，等價(jià)于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();
