. Following INIs are removed
. session.hash_function
. session.hash_bits_per_charactor
. session.hash_bits_per_character
. session.entropy_file
. session.entropy_length
. New INIs and defaults
. session.sid_length (Number of session ID characters - 22 to 256.
(php.ini-* default: 26 Compiled default: 32)
. session.sid_bits_per_character (Bits used per character. 4 to 6.

Length of old session ID string is determined as follows
. Length of old session ID string is determined as follows
. Used hash function's bits.
. session.hash_function=0 - MD5 128 bits (This was default)
. session.hash_function=1 - SHA1 192 bits
. session.hash_function=1 - SHA1 160 bits
. Bits per character. (4, 5 or 6 bits per character)
. Examples
MD5 and 4 bits = 32 chars, ceil(128/4)=32
MD5 and 5 bits = 26 chars, ceil(128/5)=26
MD5 and 6 bits = 22 chars, ceil(128/6)=22
SHA1 and 4 bits = 48 chars, ceil(192/4)=48
SHA2 and 5 bits = 39 chars, ceil(192/5)=39
SHA1 and 6 bits = 32 chars, ceil(192/6)=32
SHA1 and 4 bits = 40 chars, ceil(160/4)=40
SHA1 and 5 bits = 32 chars, ceil(160/5)=32
SHA1 and 6 bits = 27 chars, ceil(160/6)=27
and so on.
. session_start() returns FALSE and no longer initializes $_SESSION when
it failed to start session.
