aggregate_info

(no version information, might be only in CVS)aggregate_info --

Returns an associative array of the methods and properties from

each class that has been aggregated to the object

Description

array aggregate_info (object object)

Will return the aggregation information for a particular object

as an associative array of arrays of methods and properties. The

key for the main array is the name of the aggregated class.

For example the code below

Пример 1. Using aggregate_info()


<?php

class Slicer {
var $vegetable;

function Slicer($vegetable)
{
$this->vegetable = $vegetable;
}

function slice_it($num_cuts)
{
echo "Doing some simple slicing\n";
for ($i=0; $i < $num_cuts; $i++){
// do some slicing
}
}
}

class Dicer {
var $vegetable;
var $rotation_angle = 90; // degrees

function Dicer($vegetable)
{
$this->vegetable = $vegetable;
}

function dice_it($num_cuts)
{
echo "Cutting in one direction\n";
for ($i=0; $i < $num_cuts; $i++){
// do some cutting
}
$this->rotate($this->rotation_angle);
echo "Cutting in a second direction\n";
for ($i=0; $i < $num_cuts; $i++){
// do some more cutting
}
}

function rotate($deg)
{
echo "Now rotating {$this->vegetable} {$deg} degrees\n";
}

function _secret_super_dicing($num_cuts)
{
// so secret we cannot show you ;-)
}
}

$obj = new Slicer('onion');
aggregate($obj, 'Dicer');
print_r(aggregate_info($obj));
?>

Will produce the output

Array
(
[dicer] => Array
(
[methods] => Array
(
[0] => dice_it
[1] => rotate
)
[properties] => Array
(
[0] => rotation_angle
)
)
)

As you can see, all properties and methods of the

Dicer class have been aggregated

into our new object, with the exception of the class

constructor and the method _secret_super_dicing
