Examples

Example #1 Using aggregate_info()


<?php

class Slicer {
    var $vegetable;

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

    function slice_it($num_cuts) 
    {
        echo "Doing some simple slicing\n";
        for ($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));
?>

The above example will 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

aggregate() - Dynamic class and object aggregation of methods and properties
aggregate_methods() - Dynamic class and object aggregation of methods
aggregate_methods_by_list() - Selective dynamic class methods aggregation to an object
aggregate_methods_by_regexp() - Selective class methods aggregation to an object using a regular expression
aggregate_properties() - Dynamic aggregation of class properties to an object
aggregate_properties_by_list() - Selective dynamic class properties aggregation to an object
aggregate_properties_by_regexp() - Selective class properties aggregation to an object using a regular expression
deaggregate() - Removes the aggregated methods and properties from an object
