RE: [PHP] Shopping with variables

why not use serialized arrays stored in cookies to store a growing list of things that the user is purchasing? then, it'd be as easy as having this array stored as a single cookie... ;) $items = array( #indexed by item ID '1003045' => array( 'name' =>'The best movie', 'type'=>'DVD', 'quan'=>1, ), ); then you could loop thru the array and have all the information right at your fingertips print "You ordered $items[$current]['quan'] of $items[$current]['type']"; > -----Original Message----- > From: John Monfort [mailto:monfort@kahuna.sdsu.edu] > Sent: Wednesday, May 16, 2001 9:02 AM > To: Ralph Guzman > Cc: Tarrant Costelloe; php-general@lists.php.net > Subject: RE: [PHP] Shopping with variables > > > > > That will work, assuming the user is not allowed to purchase multiple > items... > > -John > > On Wed, 16 May 2001, Ralph Guzman wrote: > > > Might want to reconsider the way you are doing this, since this may not be > > the most efficient way.
