utilities

A basic set of utility classes for use in other modules.

\tr33m4n\Utilities\Data\DataCollection

A simple, iterable collection for storing data

• $dataCollection->set Set an item to the data collection
• $dataCollection->get Get an item from the data collection
• $dataCollection->add Add a key value pair array to the data collection
• $dataCollection->has Check if an item exists in the data collection
• $dataCollection->setAll Bulk set items to the data collection
• $dataCollection->getAll Get all items set against the data collection

An array of items can also be passed to populate the data collection when instantiating. The collection can also be iterated, for example:

<?php

$dataCollection = new DataCollection([
    'test1' => 'test1',
    'test2' => 'test2'
]);

/**
 * Or 
 * 
 * $dataCollection = DataCollection::from([
 *      'test1' => 'test1',
 *      'test2' => 'test2'
 * ]);
 */

foreach ($dataCollection as $key => $value) {
    echo "$key : $value\n";
}

\tr33m4n\Utilities\Config\ConfigProvider

A simple configuration parser and provider. This class inherits all the functionality of a data collection, however when the class is instantiated it will aggregate config files into a nested configuration collection structure. Config paths can be passed to the constructor or defined by setting the global constant ROOT_CONFIG_PATH. The ROOT_CONFIG_PATH path will always take priority when parsing the files, so if you have a config file with the same name in the constructor path and the global path, the global will overwrite it.

The config provider comes bundled with a PHP file adapter \tr33m4n\Utilities\Config\Adapter\PhpFileAdapter. An alternative file adapter can be passed when instantiating the class.

A typical config file using the default adapter might look like:

<?php
// Filename: test1.php

return [
    'test1' => 'test1',
    'test2' => 123,
    'test3' => [
        'test1' => 'test1',
        'test2' => 123,
        'test3' => [
            'test1' => 'test1',
            'test2' => [
                'test1' => 'deep_value'
            ],
            'test3' => [
                'test1' => 'test1'
            ]
        ]
    ]
];

When parsing this configuration structure, the filename will be used for the root array key and each array item will be converted to a new \tr33m4n\Utilities\Config\ConfigCollection, this might look like:

[
    'test1' => new ConfigCollection([
        'test1' => 'test1',
        'test2' => 123,
        'test3' => new ConfigCollection([
            'test1' => 'test1',
            'test2' => 123,
            'test3' => new ConfigCollection([
                'test1' => 'test1',
                'test2' => new ConfigCollection([
                    'test1' => 'deep_value'
                ]),
                'test3' => new ConfigCollection([
                    'test1' => 'test1'
                ])
            ])
        ])
    ])
];

These values can then be accessed using the data collections get method. For example:

<?php

$deepValue = $this->configProvider->get('test1')
    ->get('test3')
    ->get('test3')
    ->get('test2')
    ->get('test1');

// $deepValue = 'deep_value'

For convenience a global helper function config is also provided which allows access to a single instance of the config provider (set in the registry). Accessing the deep_value using this would look like:

<?php

$deepValue = config('test1')->get('test3')
    ->get('test3')
    ->get('test2')
    ->get('test1');

// $deepValue = 'deep_value'
