What's the problem?

It may be just me but don't you need to do something like ItemID = array($HH); which will make ItemID[0] = $HH and then all subsequent additions to your array will work fine?

You may need to think about the order in which you do things.
session_start() will read the session data and create new variables from the session data. So if there already was a $ItemID in the session data, then the one you created ($ItemID=$HH) will be overwritten.

Session_start() is usually the first thing that happens on a page that uses sessions.

Indeed, you may need to first "declare" $ItemID as an array:
$ItemID=array();

and then add to it:

$ItemID[]=$HH;

<?php
//---------
//here is how to store array value in session
if (!isset($ItemID))
{
$ItemID= array();
}
session_register('ItemID');

$ItemID[] = $HH ;

//----------
// print ( u can an other function instead) all the value stored in the session
$a = $ItemID[0];
$y = (-1);
do
{
$y++ ;
echo $ItemID[$y]. " $y <br>";
}
while ( $a = next($ItemID) );
//----------

// good luck guyz (o)
