If you need to serialize an object for sessions or other purposes, and want to save aggregation state, extend it from a base class such as this one, and use $this->agg/$this->unagg instead of aggregate/deaggregate
<?php
class base
{
var $_aggregates = array();
function agg($agg)
{
aggregate($this,$agg);
$this->_aggregates[$agg] = 1;
}
function unagg($agg = false)
{
if ($agg)
{
deaggregate($this,$agg);
unset($this->_aggregates[$agg]);
} else
{
deaggregate($this);
$this->_aggregates = array();
}
}
}
?>
It is worth noting that class association does not work, even in PHP 4.3.0 - this ability is experimental. I'm assuming it was added in for the sake of forwards-compatibilty. Use object association instead for now.
Until it is implemented, you will receieve a parse error when attempting to use it.

Just to prevent people posting about "why it doesn't work??", etc etc etc.
For PHP5 applications, the all of the "aggregate" function family is now in runkit.
