Cora Collection
===============

[](#cora-collection)

Basic Usage
-----------

[](#basic-usage)

### Flexible interface that allows you to use your favorite format

[](#flexible-interface-that-allows-you-to-use-your-favorite-format)

```
$collection = new \Cora\Collection();
$collection->add('Hello World');
echo $collection->get(0);       // Outputs "Hello World"
echo $collection[0];            // Outputs "Hello World"
echo $collection->get("off0");  // Outputs "Hello World"
echo $collection->off0;         // Outputs "Hello World"
```

### Easily filter contents using WHERE method

[](#easily-filter-contents-using-where-method)

```
$collection = new \Cora\Collection([
    new \Classes\Event('Debit', '10/10/1980'),
    new \Classes\Event('Debit', '10/10/2001'),
    new \Classes\Event('Deposit', '02/14/2008'),
    new \Classes\Event('Debit', '10/10/1990'),
    new \Classes\Event('Debit', '10/10/2003'),
    new \Classes\Event('Deposit', '02/14/2004')
]);
$this->assertEquals(6, $collection->count());
$this->assertEquals(4, count($collection->where('name', 'Debit')));
$this->assertEquals(2, count($collection->where('name', 'Deposit')));
$this->assertEquals(4, count($collection->where('timestamp', new \DateTime('01/01/2000'), '>=')));
```

### Can set an object property or associative array key as the primary for access

[](#can-set-an-object-property-or-associative-array-key-as-the-primary-for-access)

Here we pass in "name" as the second constructor argument:

```
$collection = new \Cora\Collection([
    new \Classes\User('User1', 'Type1'),
    new \Classes\User('User2', 'Type1'),
    new \Classes\User('User3', 'Type2'),
    new \Classes\User('User4', 'Type2'),
    new \Classes\User('User5', 'Type1'),
    new \Classes\User('User6', 'Type3')
], 'name');

$this->assertEquals('User3', $collection->User3->name);
$this->assertEquals('Type2', $collection->User3->type);
$this->assertEquals('Type2', $collection->get('User3')->type);
```
