The Collection.php class in Prologue Support comes with some additional functions., (*8)
filterBy($key, $value)
Used to filter for records which have a specific value set for a given key., (*9)
$data = array(
array('name' => 'foo', 'age' => 21),
array('name' => 'bar', 'age' => 20),
array('name' => 'baz', 'age' => 9),
);
$collection = new Prologue\Support\Collection($data);
// Will return only records with an age of 20.
$items = $collection->filterBy('age', 20)->all();
orderBy($key, $direction)
Used to order records by a given key., (*10)
$data = array(
array('name' => 'foo', 'age' => 21),
array('name' => 'bar', 'age' => 20),
array('name' => 'baz', 'age' => 9),
);
$collection = new Prologue\Support\Collection($data);
// Will order the records by its age in ascending order.
$items = $collection->orderBy('age')->all();

$items = $collection->orderBy('age', 'desc')->all();
MessageBag
The MessageBag class in Prologue Support offers the ability to add arrays or other MessageBags as messages., (*12)
$bag = new Prologue\Support\MessageBag;
$bag->add('error', array(
'email' => 'Incorrect email address',
'url' => 'Incorrect url',
));
$messages = $bag->get('error');
Now $messages equals to:, (*13)
array(
array(
'email' => 'Incorrect email address',
'url' => 'Incorrect url',
)
