Installation
------------

[](#installation)

```
$ composer require alexeyshockov/colada-x
```

Usage
-----

[](#usage)

With ColadaX:

```
$activeUsers = array_filter($users, \Colada\x()->isActive());
```

```
$role = 'ADMIN';
$administrators = array_filter($users, \Colada\x()->hasRole($role));
```

Instead of pure PHP:

```
$activeUsers = array_filter($users, function ($user) {
    return $user->isActive();
});
```

```
$role = 'ADMIN';
$activeUsers = array_filter($users, function ($user) use ($role) {
    return $user->hasRole($role);
});
```

Useful together
---------------

[](#useful-together)

Some code examples for your imagination.

### Laravel 5 Collections

[](#laravel-5-collections)

```
$activeUsers = $users->filter(\Colada\x()->isActive());
```

### PHP Collection ([schmittjoh/php-collection](https://github.com/schmittjoh/php-collection/))

[](#php-collection-schmittjohphp-collection)

```
$activeUsers = $users->filter(\Colada\x()->isActive());
```

### functional-php ([lstrojny/functional-php](https://github.com/lstrojny/functional-php))

[](#functional-php-lstrojnyfunctional-php)

The library already has `partial_method` function, but it's less powerful.

```
use Functional as F;

$activeUsers = F\select($users, \Colada\x()->isActive());
```

Less useful, but still
----------------------

[](#less-useful-but-still)

### Doctrine 2 Collections (Symfony 2, Doctine 2 ORM, etc.)

[](#doctrine-2-collections-symfony-2-doctine-2-orm-etc)

```
// __asClosure() is needed because all Doctrine's methods accept only \Closure instances :(
$hasActiveUsers = $users->exists(\Colada\x()->isActive()->__asClosure());
```

### Laravel 4 Collections

[](#laravel-4-collections)

The same problem as described above with Doctrine.

Alernatives
-----------

[](#alernatives)

If you need only the basic functionaly, take a look at `invoke()`, `invoke_first()`, `invoke_if()`, `invoke_last()`, `invoker()` from a great [functional-php library](https://github.com/lstrojny/functional-php).
