This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.
Thank you for the report, and for helping us make our documentation

"Session name can't consist only from digits, at least one letter must
be present. Otherwise new session id is generated every time."

There should be a big fat warning about this in the manual.

Session name can NOT be a plain number.
No checks will be added since that'd make the code slower for no real
gain.

This happens because PHP turns a numeric session name
into an array index inside $_COOKIE and we're doing an
zend_hash_find() instead of a zend_hash_index_find().
(ext/session/session.c, line 1098).
We can probably fix the bug by doing a
zend_hash_index_find() instead if the session name
successfully converts to a integer.

Here's a simple workaround:
<?php
// This name works.
//session_name('A9');
// This name doesn't...
session_name('99');
// Force the last session id, not the detected one.
session_id($_COOKIE[session_name()]);
session_start();
echo '
Session Name: ', session_name(), '<br />
Session ID: ', session_id(), '<br />
Cookie: ', $_COOKIE[session_name()];
?>
Removing the session_id() line though, shows that the cookie is still
being properly set.

Description:
------------
When you use a session name that has only numbers, each call to
session_start seems to regenerate a new session id, so the session does
not persist.
The code below can be loaded and refreshed to reproduce the behaviour
Reproduce code:
---------------
<?php
//This name works
//session_name('A9');
//This name doesn't
session_name('99');
session_start();
echo 'Session Name: '.session_name().'<br />';
echo 'Session Id: '.session_id().'<br />';
?>
Expected result:
----------------
Session Name: 99
Session Id: {{a sid that remains the same between each refresh }}
Actual result:
--------------
Session Name: 99
Session Id: {{a different sid each refresh}}
