How to use it

Couple of examples.

Fluent arrays:

$result = FluentArray::from($users)
             ->map(Functions::extractField('name'))
             ->filter(Functions::notEmpty())
             ->unique()
             ->toArray();

Fluent iterator:

$result = FluentIterator::fromArray([1, 2, 3])
             ->cycle()
             ->limit(10)
             ->reindex()
             ->toArray(); // [1, 2, 3, 1, 2, 3, 1, 2, 3, 1]

Fluent functions:

$product = new Product(['name' => 'super phone']);

$function = FluentFunctions::extractField('name')
      ->removePrefix('super')
      ->prepend(' extra')
      ->append('! ')
      ->surroundWith("***");

$result = Functions::call($function, $product); //=> '*** extra phone! ***'
$phones = Arrays::filter($products, FluentFunctions::extractField('type')->equals('PHONE'));

Extract (from Functions):

$cities = Arrays::map($users, Functions::extract()->getAddress('home')->city);

Clock:

$string = Clock::now()
    ->plusYears(1)
    ->plusMonths(2)
    ->minusDays(3)
    ->format();

Comparators:

$product1 = new Product(['name' => 'b']);
$product2 = new Product(['name' => 'c']);
$product3 = new Product(['name' => 'a']);

$result = Arrays::sort([$product1, $product2, $product3], Comparator::compareBy('name'));

Fluent assertions for arrays:

$animals = ['cat', 'dog', 'pig'];
Assert::thatArray($animals)->hasSize(3)->contains('cat');

Fluent assertions for strings:

Assert::thatString("Frodo")
     ->startsWith("Fro")
     ->endsWith("do")
     ->contains("rod")
     ->doesNotContain("fro")
     ->hasSize(5);

Mocking:

$mock = Mock::create();
Mock::when($mock)->someMethod('arg')->thenReturn('123');

$result = $mock->someMethod('arg');

$this->assertEquals('123', $result);
Mock::verify($mock)->method('arg');

Exception assertions:

$foo = new Foo();

CatchException::when($foo)->method();

CatchException::assertThat()->isInstanceOf("FooException");

This is just a taste of Ouzo. Look at the documentation for more goodies.
