isset($_SESSION['foo']) vs $this->session->has_userdata('foo') - ôkio - 04-22-2015
Hello,
I'm just starting to use CI, and I'm wondering what's the good way of dealing with session.
I wrote things like that so far :
PHP Code:
$this->session->foo = 'bar';
...
if ($this->session->foo == 'bar')
...
if ($this->session->has_userdata('foo'))
...
But in the doc, there is a note :
Quote:This is a legacy method kept only for backwards compatibility with older applications. It is just an alias for isset($_SESSION[$key]) - please use that instead.
I'm not sure to understand why the use of has_userdata is not recommended. Why can I use a magic object "session" to set and retrieve data from the session, and why I should access directly to the plain vanilla $_SESSION array to test if a key exists.
Could someone explain me what should I use ?
Thanks !

You've already quoted the answer - backwards compatibility.

@Narf
IMO $this->session->has_userdata('foo') and the other methods should not be deprecated in the future. It is a good abstration.
