Put all the ids into a variable called  ids and separate them with a        ids    1 2 3 4 5 6     Pass them like so    url     ids   ids      Process them    ids   explode        GET  ids

The usual way to do this in PHP is to put id   in your URL instead of just id   http   link foo php id   1 amp id   2 amp id   3   Then   GET  id   will be an array of those values  It s not especially pretty  but it works out of the box

You can get them using the Query String    idArray   explode   amp     SERVER  QUERY STRING       This will give you    idArray 0     id 1    idArray 1     id 2    idArray 2     id 3     Then   foreach   idArray as  index   gt   avPair      list  ignore   value    explode       avPair      id  index     value      This will give you   id 0     1    id 1     2    id 2     3

You could make id a series of comma-seperated values  like this   index php id 1 2 3 amp name john  Then  within your PHP code  explode it into an array    values   explode        GET  id     print count  values      values passed      This will maintain brevity  The other  more commonly used with   POST  method is to use array-style square-brackets   index php id   1 amp id   2 amp id   3 amp name john  But that clearly would be much more verbose

When you don t want to change the link  e g  foo php id 1 amp id 2 amp id 3  you could probably do something like this  although there might be a better way        id arr   array    foreach  explode   amp      SERVER  QUERY STRING    as  tmp arr param         split param   explode       tmp arr param       if   split param 0      id              id arr     urldecode  split param 1            print r  id arr

I think i know what you mean  if you want to send an array through a URL you can use serialize  for example    foo   array 1 2 3    serialized array   serialize  foo    url    http   www foo whatever page php vars   urlencode  serialized array     and on page php   vars   unserialize   GET  vars

You can specify an array in your HTML this way    lt input type  hidden  name  id    value  1   gt   lt input type  hidden  name  id    value  2   gt   lt input type  hidden  name  id    value  3   gt    This will result in this   GET array in PHP   array     id    gt  array      0   gt  1      1   gt  2      2   gt  3         Of course  you can use any sort of HTML input  here  The important thing is that all inputs whose values you want in the  id  array have the name id
