$dsn,string
$user,string
$password,int
$cursor_option = SQL_CUR_USE_DRIVER): resource|false
Opens a persistent database connection.
This function is much like
odbc_connect(), except that the connection is
not really closed when the script has finished. Future requests
for a connection with the same dsn,
user, password
combination (via odbc_connect() and
odbc_pconnect()) can reuse the persistent
connection.
參數
See odbc_connect() for details.
返回值
Returns an ODBC connection, 或者在失敗時返回 false.
error.
註釋
