# ramda-php
This is a PHP implementation of ramda.js - a functional programming library. (http://ramdajs.com/)
So far only the curry functions and part of the functions implemented. The library is capable of doing the what's in the ramda.js examples.

### Introduced Methods
R::$flatten1 - flatten in non-recursive way (for 1 depth only).
### How to Use
Compose functions:
```
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'));
};
```
Use the function on data:
```
$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($tasks);
```
Outputs:
```
(
[0] => Array
(
[id] => 122
[dueDate] => 2013-11-01
[title] => Fix the bar
[priority] => high
)
[1] => Array
(
[id] => 107
[dueDate] => 2013-11-22
[title] => Fix the foo
[priority] => high
)
)
```
Note: as a defect of PHP compiler, static method ```R::$add(1,2)``` wouldn't compile. To get around, place the static method inside parenthesis ```(R::$add)(1,2)```
Curry functions:
(Note: ```R::$_``` is the placeholder parameter.)
```
$f3 = function($a, $b, $c) {
return $a*2+$b*3+$c*4;
};
$c = R::curry($f3);
$cc = $c(R::$_,2,R::$_);
print_r($cc(1,3));
```
Outputs:
```
20
```
