Gets the aggregation information for the given object.
Returns the aggregation information as an associative array of arrays of methods and properties. The key for the main array is the name of the aggregated class.
Example #1 Using aggregate_info() 以上例程会输出：
<?php
class Slicer {
var $vegetable;
function Slicer($vegetable)
{
$this->vegetable = $vegetable;
}
function slice_it($num_cuts)
{
echo "Doing some simple slicing
";
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
";
for ($i=0; $i < $num_cuts; $i++) {
// do some cutting
}
$this->rotate($this->rotation_angle);
echo "Cutting in a second direction
";
for ($i=0; $i < $num_cuts; $i++) {
// do some more cutting
}
}
function rotate($deg)
{
echo "Now rotating {$this->vegetable} {$deg} degrees
";
}
function _secret_super_dicing($num_cuts)
{
// so secret we cannot show you ;-)
}
}
$obj = new Slicer('onion');
aggregate($obj, 'Dicer');
print_r(aggregate_info($obj));
?>
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()
