thinkphp怎么连接数据库

Answer 1

数据库的配置文件有多种定义方式:
第一种:在项目配置文件里面定义

1234567891011return array( 'DB_TYPE'=> 'mysql', 'DB_HOST'=> 'localhost', 'DB_NAME'=>'thinkphp', 'DB_USER'=>'root', 'DB_PWD'=>'', 'DB_PORT'=>'3306', 'DB_PREFIX'=>'think_', // 其他项目配置参数……… );
第二种 在模型类里面定义

12345678910protected $connection = array( 'dbms' => 'mysql', 'username' => 'username', 'password' => 'password', 'hostname' => 'localhost', 'hostport' => '3306', 'database' => 'dbname' ); // 或者使用下面的定义 protected $connection = "mysql://username:passwd@localhost:3306/DbName";
第三种 使用数组传参数

123456789$DSN = array( 'dbms' => 'mysql', 'username' => 'username', 'password' => 'password', 'hostname' => 'localhost', 'hostport' => '3306', 'database' => 'dbname' ); $db = new Db($DSN);
