Beispiele
Beispiel #1 Using aggregate_info()
<?phpclass 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));
?>Das oben gezeigte Beispiel erzeugt folgendeAusgabe:
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
