Functional programming library for PHP

Underscore

, _(*1)

Functional programming library for PHP, _(*2)

Code example

Library aims to be as easy to use as possible. Here is example of doing some not-so-meaningful operations to show off:, _(*3)

    Underscore::from([1,2,3,4,5])
            // convert array format
        ->map(function($num) { return ['number' => $num];})
            // filter out odd elements
        ->filter(function($item) { return ($item['number'] % 2) == 0;})
            // vardump elements
        ->invoke(function($item) { var_dump($item);})
            // changed my mind, I only want numbers
        ->pick('number')
            // add numbers to 1000
        ->reduce(function($sum, $num) { $sum += $num; return $sum; }, 1000)
            // take result
        ->value();
            // 1006

Motivation

Originaly I needed functional programming magic for other project, so had to pick one lib or write my own., _(*4)

There is several PHP ports of UnderscoreJS, however none of those fit my requirements (nice code, easy to write, standardized): - brianhaveri/Underscore.php - not maintained, messy code - Anahkiasen/underscore-php - Laravel4 package => incompatible with PSR-2, _(*5)
