Motivation
----------
I did create this project to explore **Functional Programming**.
**This project doesn't use any loop!**
Install
-------
```bash
composer require sergiors/functional "dev-master"
```
How to use
----------
```php
use Sergiors\Functional as F;
$addFourNumbers = funciton ($a, $b, $c, $d) {
return $a + $b + $c + $d;
};
$partialAddFourNumbers = F\partial($addFourNumbers);
$f = $partialAddFourNumbers(1, 2);
$g = $f(3);
echo $g(4); // => 10
```
You can hold native functions with `Sergiors\Funcional\hold`.
```php
use Sergiors\Functional as F;
$implode = F\hold('implode', ',');
echo $implode(['a', 'b']); // => a,b
// something more complex
$pipe = F\pipe(
F\hold('array_slice', F\_, 2),
F\hold('array_map', function ($x) {
return $x * 2;
}),
F\hold('implode', ',')
);
echo $pipe([10, 20, 30, 40, 50]); // => 60,80,100
```
`Sergiors\Functional\_` is the placeholder for payload. If you don't set the placeholder, the payload will be last argument.
Collection
----------
You can wrap an array with `Sergiors\Functional\Collection` to use fluent interface.
```php
use Sergiors\Functional\Collection;
$ls1 = new Collection([1, 2, 3, 4, 5, 6]);
$ls2 = $ls1->filter(function ($x) {
return $x > 2;
})->map(function ($x) {
return $x + 1;
});
print_r($ls1->toArray()); // => [1, 2, 3, 4, 5, 6]
print_r($ls2->toArray()); // => [4, 5, 6, 7]
```
