所以当我尝试在我的 Mapper 类的构造函数中创建我的数据库时,我总是得到一个 pdo 异常。在这条线上:
$this->db = new PDO($dsn, $db_config['username'], $db_config['password']);
这是我的 dsn 创作:
$db_config = array(
'driver' => 'pgsql',
'username' => $dbUser,
'password' => $dbPassword,
'schema' => 'r0628740',
'dsn' => array(
'host' => 'gegevensbanken.khleuven.be',
'dbname' => '2TX31',
'port' => '51314',
)
);
最后是我的构造函数:
public function __construct(){
global $db_config;
$dsn = $db_config['driver'] . ':';
foreach($db_config['dsn'] as $key => $value){
$dsn .= $key . '=' . $value . ';';
}
try{
$this->db = new PDO($dsn, $db_config['username'], $db_config['password']);
$this->db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
if(($db_config['driver'] == 'pgsql') && isset($db_config['schema'])){
$this->db->query(sprintf("SET SEARCH_PATH TO %s"), $db_config['schema']);
}
}catch (PDOException $e){
var_dump($e->getLine());
error_log($e->getMessage());
}
}
