What happened?

memcached support is broken in CI 4.7.0 because of the accidental change to this line:

There was a commit done on 1/1/2026:
772eaf4
The original line was "if (empty($this->savePath)) {" new line is doing not empty which is not correct.

Steps to Reproduce

Upgrade to CI 4.7.0 and in your .env file set:

session.driver = 'CodeIgniter\Session\Handlers\MemcachedHandler'
session.expiration = 7200
session.savePath = 'localhost:11211'

Try and access CodeIgniter and it will say:

CodeIgniter\Session\Exceptions\SessionException
Session: No save path configured.

And the error points to:

66         if ($this->savePath !== '') {
67             throw SessionException::forEmptySavepath();
68         }

Expected Output

If we change "if ($this->savePath !== '') {" to "if ($this->savePath === '') {" in the MemcachedHandler.php then it works as expected.

Anything else?
