/**
 * Session handler using a PDO connection to read and write data.
 *
 * It works with MySQL, PostgreSQL, Oracle, SQL Server and SQLite and implements
 * different locking strategies to handle concurrent access to the same session.
 * 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.

         *
         * ---------- 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).`
