unsetting some session data in codeigniter
提问by Udders
I am saving some data in a session, and certain points in my websites, I am giving the user the option to removes certain parts of the session based on the array key, the array I get when I do,
我在会话中保存了一些数据，并在我的网站中保存了某些点，我让用户可以选择根据数组键删除会话的某些部分，我这样做时得到的数组，
print_r($this->session->userdata('shortlist');this leaves me the the following output,
print_r($this->session->userdata('shortlist');这给我留下了以下输出，
Array ( [0] => Array (
[id] => 40
[name] => Namey Name
[location] => location is a place
[talent] => voice over
[image] => ./media/uploads/headshots/width_60_249613_10150280293315435_717615434_9570480_8341358_n.jpg ) );
How can I remove this from my shortlist session? I have tried doing the following, but to no avail,
如何从我的候选列表会话中删除它？我曾尝试执行以下操作，但无济于事，
unset($this->session->userdata('shortlist')[0]);
unset($this->session->userdata('shortlist')[0]);
