Hi Alex,
(sorry Nick, if you'd rather I moved this conversation off list just
yell :))
Visit http://www.phpbuilder.com/columns/ying20000602.php3 and
fetch down the ying.zip he has on there. That contains session_mysql.php
which you need to bung somewhere on your system. I made some changes
because its a little broken in one place and a little inefficient in another.
1) I added this to the very top;
if ( defined("SESSION_HANDLER") )
{
return;
}
else
{
define("SESSION_HANDLER", "Yes");
}
2) In sess_read() you need to change return false; into return "" otherwise
you'll get a seg fault in Apache every time a new session is needed.
3) I changed the insert into query in sess_write() to be a replace into
query, which should save on updates (the present system tries to insert and
if it fails then it does an update instead. I replaced the insert with
replace so that the db can do all that).
4) I added the file to the auto_prepend variable in php.ini so that its
automatically called for any script (hence the addition in part 1 to
protect against it getting called twice for any reason)
Anyway, it seems to work a treat for us.
Steve.
