Re: Missing session vars when doing var_dump()

Thanks for your input Bobby I was using mysql_fetch_array() but changed to mysql_fetch_assoc() The funny thing is, I have a page that does the var_dump() and all I'm doing is refreshing the page and sometimes I get 18 other times 16 variables Gavin Auckland, New Zealand > -----Original Message----- > From: Bobby Patel [SMTP:anup_patel@rogers.com] > Sent: Friday, March 21, 2003 11:29 AM > To: php-general@lists.php.net > Subject: [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.
