Object Aggregation Functions

Коментарии

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.
