如何将数据库类与数组连接起来

Question

如何将我的数据库类函数连接到另一个脚本？我需要在不更改连接文件的每个文件的情况下完成它.

这是我的配置文件(conn.php):

define('DB_HOST', "localhost"); 
define('DB_TYPE', "mysql"); 
define('DB_USER', "user"); 
define('DB_PASS', "123456"); 
define('DB_NAME', "dbuser"); 

这是我需要更改为DEFINE连接的配置:

include_once('../conn.php'); # is the file with the connection

$config = array();
$config['database']['host'] = 'localhost';    # I tried with .DB_HOST.
$config['database']['user'] = '';        # I tried with .DB_TYPE.
$config['database']['password']  = '';      
$config['database']['database'] = '';

您已经定义了常量,因此无需将其包装在引号或连接中.

使用引号将被视为字符串文字.

$config = array();
$config['database']['host'] = DB_HOST;
$config['database']['user'] = DB_USER;
$config['database']['password']  = DB_PASS;      
$config['database']['database'] = DB_NAME;
