范例

Example #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 ";
        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));
?>

以上例程会输出:

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()
