这是 ramda.js 的 PHP 实现——一个函数式编程库。(http://ramdajs.com/)

到目前为止，只实现了 curry 函数和部分函数。该库可以执行 ramda.js 示例中的操作。

引入方法

R::$flatten1 - 以非递归方式展开（仅限于1层）。

如何使用

组合函数

  require_once 'ramda.php';
  
  $getIncompleteTaskSummaries = function($membername) {
    return (R::$compose)(
      (R::$sortBy)((R::$prop)('dueDate')),
      (R::$map)((R::$pick)(['id', 'dueDate', 'title', 'priority'])),
      (R::$reject)((R::$propEq)('complete', true)),
      (R::$filter)((R::$propEq)('username', $membername)),
      (R::$prop)('tasks'));
  };

在数据上使用函数

  $data = [
      'result' => "SUCCESS",
      'interfaceVersion' => "1.0.3",
      'requested' => "10/17/2013 15:31:20",
      'lastUpdated' => "10/16/2013 10:52:39",
      'tasks' => [
          ['id' => 104, 'complete' => false,            'priority' => "high",
                    'dueDate' => "2013-11-29",      'username' => "Scott",
                    'title' => "Do something",      'created' => "9/22/2013"],
          ['id' => 105, 'complete' => false,            'priority' => "medium",
                    'dueDate' => "2013-11-22",      'username' => "Lena",
                    'title' => "Do something else", 'created' => "9/22/2013"],
          ['id' => 107, 'complete' => false,             'priority' => "high",
                    'dueDate' => "2013-11-22",      'username' => "Mike",
                    'title' => "Fix the foo",       'created' => "9/22/2013"],
          ['id' => 108, 'complete' => false,            'priority' => "low",
                    'dueDate' => "2013-11-15",      'username' => "Punam",
                    'title' => "Adjust the bar",    'created' => "9/25/2013"],
          ['id' => 110, 'complete' => false,            'priority' => "medium",
                    'dueDate' => "2013-11-15",      'username' => "Scott",
                    'title' => "Rename everything", 'created' => "10/2/2013"],
          ['id' => 112, 'complete' => true,             'priority' => "high",
                    'dueDate' => "2013-11-27",      'username' => "Lena",
                    'title' => "Alter all quuxes",  'created' => "10/5/2013"],
          ['id' => 122, 'complete' => false,             'priority' => "high",
                    'dueDate' => "2013-11-01",      'username' => "Mike",
                    'title' => "Fix the bar",       'created' => "9/22/2013"],
          ['id' => 123, 'complete' => true,             'priority' => "high",
                    'dueDate' => "2013-11-22",      'username' => "Mike",
                    'title' => "Fix the foobar",       'created' => "9/22/2013"],

      ]
  ];
  $tasks = $getIncompleteTaskSummaries("Mike")($data);
  print_r($tasks);

输出

(
    [0] => Array
        (
            [id] => 122
            [dueDate] => 2013-11-01
            [title] => Fix the bar
            [priority] => high
        )

    [1] => Array
        (
            [id] => 107
            [dueDate] => 2013-11-22
            [title] => Fix the foo
            [priority] => high
        )

)

注意：由于PHP编译器的缺陷，静态方法 R::$add(1,2) 不会编译。为了解决这个问题，请将静态方法放在括号内 (R::$add)(1,2)

curry函数

(注意：R::$_ 是占位符参数。)

  $f3 = function($a, $b, $c) {
      return $a*2+$b*3+$c*4;
  };
  $c = R::curry($f3);
  $cc = $c(R::$_,2,R::$_);
  print_r($cc(1,3));

输出

(更多示例可以在 /tests 文件夹中找到。)
