当我想在codeigniter 3中设置会话数据时,它说错误就像：
A PHP Error was encountered Severity: Warning Message: mkdir(): Invalid path Filename: drivers/Session_files_driver.PHP Line Number: 117 Backtrace: File: C:\xampp\htdocs\ci-test\application\controllers\login.PHP Line: 7 Function: __construct File: C:\xampp\htdocs\ci-test\index.PHP Line: 292 Function: require_once
以下是要设置会话数据的代码.
$sess_array = array(
'id' => 1,'username' => 'bikramkc.kc@gmail.com'
);
$this->session->set_userdata($sess_array);
