README

A set of interfaces and traits to speed up the creation of collections.

Requirements

• PHP >= 5.4

Installation

The recommended way to install is through composer.

Just create a composer.json file for your project:

{
    "require": {
        "ebidtech/collection": "@stable"
    }
}

Tip: browse ebidtech/collection page to choose a stable version to use, avoid the @stable meta constraint.

And run these two commands to install it:

$ curl -sS https://getcomposer.org/installer | php
$ composer install

Now you can add the autoloader, and you will have access to the library:

<?php

require 'vendor/autoload.php';

Usage

Collection class example:

use EBT\Collection\CollectionDirectAccessInterface;
use EBT\Collection\CountableTrait;
use EBT\Collection\DirectAccessTrait;
use EBT\Collection\EmptyTrait;
use EBT\Collection\GetItemsTrait;
use EBT\Collection\IterableTrait;

/**
 * TestCollection
 */
class TestCollection implements CollectionDirectAccessInterface
{
    use CountableTrait;
    use DirectAccessTrait;
    use EmptyTrait;
    use GetItemsTrait;
    use IterableTrait;

    /**
     * @var array
     */
    protected $items = array(
        'test1' => 'val1',
        'test2' => 'val2',
        'test3' => 'val3'
    );
}

From outside you can:

• iterate (due to IterableTrait)
• direct access using get() (due to DirectAccessTrait)
• use count() (due to CountableTrait)

Outside access example:

$collection = new TestCollection();
echo count($collection); // will print 3
echo $collection->get('test1');  // will print val1
foreach ($collection as $key => $val) {
    // will result in:
    // test1 val1
    // test2 val2
    // test3 val3
    echo sprintf("%s %s", $key, $val);
}

Notes:

• Traits use have an abstract getCollection() method that needs to be implemented on collection class, the GetCollectionTrait makes a simple implementation, you can override it if the property that holds the internal array is not named collection
