* Locking is necessary to prevent loss of data due to race conditions and to keep
* the session data consistent between read() and write(). With locking, requests
* for the same session will wait until the other one finished writing. For this
* reason it's best practice to close a session as early as possible to improve
* concurrency. PHPs internal files session handler also implements locking.
*
* Attention: Since SQLite does not support row level locks but locks the whole database,
* it means only one session can be accessed at a time. Even different sessions would wait
* for another to finish. So saving session in SQLite should only be considered for
* development or prototypes.
*
* Session data is a binary string that can contain non-printable characters like the null byte.
* For this reason it must be saved in a binary column in the database like BLOB in MySQL.
* Saving it in a character column could corrupt the data. You can use createTable()
* to initialize a correctly defined table.

* Explanation of the session ID regular expression: `/^[a-zA-Z0-9,-]{22,250}$/`.
*
* ---------- Part 1
*
* The part `[a-zA-Z0-9,-]` is related to the PHP ini directive `session.sid_bits_per_character` defined as 6.
* See https://www.php.net/manual/en/session.configuration.php#ini.session.sid-bits-per-character.
* Allowed values are integers such as:
* - 4 for range `a-f0-9`
* - 5 for range `a-v0-9`
* - 6 for range `a-zA-Z0-9,-`
*
* ---------- Part 2
*
* The part `{22,250}` is related to the PHP ini directive `session.sid_length`.
* See https://www.php.net/manual/en/session.configuration.php#ini.session.sid-length.
* Allowed values are integers between 22 and 256, but we use 250 for the max.
*
* Where does the 250 come from?
* - The length of Windows and Linux filenames is limited to 255 bytes. Then the max must not exceed 255.
* - The session filename prefix is `sess_`, a 5 bytes string. Then the max must not exceed 255 - 5 = 250.
*
* ---------- Conclusion
*
* The parts 1 and 2 prevent the warning below:
* `PHP Warning: SessionHandler::read(): Session ID is too long or contains illegal characters. Only the A-Z, a-z, 0-9, "-", and "," characters are allowed.`
*
* The part 2 prevents the warning below:
* `PHP Warning: SessionHandler::read(): open(filepath, O_RDWR) failed: No such file or directory (2).`
