sid_bits_per_character
......................

**type**: ``integer``

This determines the number of bits in the encoded session ID character. The possible
values are ``4`` (0-9, a-f), ``5`` (0-9, a-v), and ``6`` (0-9, a-z, A-Z, "-", ",").
The more bits results in stronger session ID. ``5`` is recommended value for
most environments.

If not set, ``php.ini``'s `session.sid_bits_per_character`_ directive will be relied on.

.. deprecated:: 7.2

The ``sid_bits_per_character`` option was deprecated in Symfony 7.2. No alternative
is provided as PHP 8.4 has deprecated the related option.

sid_length
..........

**type**: ``integer``

This determines the length of session ID string, which can be an integer between
``22`` and ``256`` (both inclusive), ``32`` being the recommended value. Longer
session IDs are harder to guess.

If not set, ``php.ini``'s `session.sid_length`_ directive will be relied on.

This is useful to get that cookie in the CLI context or when using PHP runners
like Roadrunner or Swoole.
