aggregate_properties
For PHP5 applications, the aggregate functionality available through classkit has been incorporated into and replaced by runkit. Per the classkit page of the PHP manual:
"Note: This extension has been replaced by runkit, which is not limited to class manipulation but has function manipulation, as well."
http://php.net/manual/en/ref.runkit.php
Per the runkit page:
" This package is meant as a feature added replacement for the classkit package. When compiled with the --enable-runkit=classkit option to ./configure, it will export classkit compatible function definitions and constants."

A note for those who may be implementing projects in PHP4 using aggregate(); these functions do not exist in PHP5. For similar functionality, you can try using the Classkit extension:

Note that even if this can be used to emulate multiple inheritance to some extent, an object in PHP can only be subclass of the class used in the class declaration and no other.
<?php
class A {}
class B {}
class C extends A
{
function C()
{
aggregate($this, 'B'); // emulate multiple inheritance
}
}
$c = new C;
echo (int)is_subclass_of($c, 'B');
/*
Output: 0
*/
?>

YES you can use aggregation functions to simulate multiple inheritence.
function foo()
{
aggregate($this, "bar");
bar::bar();
}
