FunctionalPHP (Yeah, need to find a better name)

A small PHP sets of functional methods inspired by Underscore.js.

Example

Given the following list of objects:

$devs = array(
    array(
        'name' => "Gianpiero",
        'last' => "Fiorelli",
        'skills' => array('CSS', 'JavaScript', 'PHP', 'HTML')
    ),
    array(
        'name' => "Simone",
        'last' => "Di Maulo",
        'skills' => array('PHP', 'Ruby', 'CSS', 'MySQL')
    ),
    array(
        'name' => "Gianluca",
        'last' => "Bargelli",
        'skills' => array('Ruby', 'JavaScript', 'PHP', 'HTML', 'CSS')
    ),
    array(
        'name' => "Giulio",
        'last' => "De Donato",
        'skills' => array('CSS', 'JavaScript', 'PHP', 'HTML')
    ),
    array(
        'name' => "Erin",
        'last' => "Hima",
        'skills' => array('PHP', 'MySQL')
    ),
);

we want to select all developers whose names begins with a 'g', does not know 'Ruby' and, finally, return a list of their names:

$result = Core::chain($devs)
            ->select(function($el) { return strtolower(substr($el['name'], 0, 1)) == "g"; })
            ->reject(function($el) { return in_array("Ruby", $el['skills']); })
            ->pluck('name')
            ->value();

Which results in:

array("Gianpiero", "Giulio");
