README

Provide PHP collection classes, with a selector to make complex queries on collections.

Beware : there is a break in compatibilty with version 1.x

Be careful to set your all packages composer.json to avoid breaking your code

Collection

Collections are classes that you can use as array.

Use it as array

The Small\Collection\Collection class is the base collection class.

You can create an empty collection :

$collection = new \Small\Collection\Collection\Collection();

Or initialize it with an array :

$collection = new \Small\Collection\Collection\Collection([1, 2, 3, 4]);

The collection has the behaviour of an array but is also an object :

$collection = new \Small\Collection\Collection\Collection([1, 2, 3, 4]);
foreach ($collection as $value) {
    echo $value;
}

Use it as an object

You can set a value for a specific key :

$collection = new \Small\Collection\Collection\Collection();
$key = 101;
$value = 'test';
$collection->set($key, $value);

And use it :

echo $collection[$key];

Check you're collection items via attributes

You can easily create your own collection with items restrictions

use Small\Collection\Collection\Attribute\CheckItemClass;

#[(CheckItemClass(CustomerEntity::class))]
class CustomerEntityCollection 
{}

or

use Small\Collection\Collection\Attribute\CheckItemInterface;

#[CheckItemInterface(CustomerInterface::class)]
class multiCustomerTypeCollection
{}

Collection classes

• Small\Collection\Collection\Collection : generic collection
• Small\Collection\Collection\NumericCollection : numeric collection

Selector

You can select arrays like it was a database table.

See Small\Collection\Selector\CollectionSelector.
