[PHP] Re: Missing session vars when doing var_dump()
I would think that they are 16 key/value pairs when the MySQL (TEXT) fields are null thus the session variables are NOT set thus NOT present. Hypothsis: I believe that your are using mysql_fetch_array($query_resource), try using the second parameter as well ie. mysql_fetch_array($query_resource, TYPE_OF_ASSOCIATION) example mysql_fetch_array($query_resource, MYSQL_ASSOC) (please see php.net for details of mysql_fetch_array). By using the second parameter, even NULL values will has a variable set. Example say you had a field called FirstName in the MySQL database. If it was NULL, then without the additional parameter you would have NO key named 'FirstName' exisiting (ie it is not set). But if you used the second parameter a key would be created with no value (ie it is set but empty). So remember, the second parameter is OPTIONAL, but it has different behaviors when you do (and do not) use it. Hopefully I cleared it up (or at least shed some light). checkout : http://www.php.net/manual/en/function.mysql-fetch-array.php Gavin Jackson [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi I have come across a strange problem.

RE: [PHP] Re: Missing session vars when doing var_dump()
Hi Bobby
The following is a copy and paste of the page I'm using to
generate the problem. I have 18 keys in the $_SESSION
variable and just by simply refreshing the page with the
following code, it returns either array(0){} or session info and
array(18){ will all the correct variables }. I must be doing
something fundamentally wrong somewhere.
Thanks very much for your willingness to help me.

Re: [PHP] Re: Missing session vars when doing var_dump()
If you it's either ALL or Nothing then I would think it has something to do
with retrieving sessions from the client (in the form of the cookie) or on
the server (in the form of the session file, default is /tmp on *nix
systems). I ran your script on my server where I have session varaibles and
I never had a problem.
I'm out of ideas now.
