Utility - Collection of various PHP utility functions.

Utility is (currently) a small collection of useful functions that are aimed to make developers' lives just a tad bit easier.



WIP Install the latest version with

$ composer require esi/utility

Standalone File

Simply drop Utility.php in any project and call include 'src/Utility/Utility.php';, where 'src/Utility' is the path to where you placed Utility.

For example:


include 'src/Utility/Utility.php';

use Esi\Utility\Utility;


Basic Usage


use Esi\Utility\Utility;


All methods of the Utility class are static. So, for example, to retrieve the information for a particular timezone:


use Esi\Utility\Utility;

$timezone = Utility::timezoneInfo('America/New_York');


    [offset] => -5
    [country] => US
    [latitude] => 40.71416
    [longitude] => -74.00639
    [dst] => 




  • Utility works with PHP 7.0.0 or above.

Submitting bugs and feature requests

Bugs and feature requests are tracked on GitHub

Issues are the quickest way to report a bug. If you find a bug or documentation error, please check the following first:

  • That there is not an Issue already open concerning the bug
  • That the issue has not already been addressed (within closed Issues, for example)


Utility accepts contributions of code and documentation from the community. These contributions can be made in the form of Issues or Pull Requests on the Utility repository.

Utility is licensed under the MIT license. When submitting new features or patches to Utility, you are giving permission to license those features or patches under the MIT license.


Before we look into how, here are the guidelines. If your Pull Requests fail to pass these guidelines it will be declined and you will need to re-submit when you?ve made the changes. This might sound a bit tough, but it is required for me to maintain quality of the code-base.

PHP Style

Please ensure all new contributions match the PSR-2 coding style guide. The project is not fully PSR-2 compatible, yet; however, to ensure the easiest transition to the coding guidelines, I would like to go ahead and request that any contributions follow them.


If you change anything that requires a change to documentation then you will need to add it. New methods, parameters, changing default values, adding constants, etc are all things that will require a change to documentation. The change-log must also be updated for every change. Also PHPDoc blocks must be maintained.


One thing at a time: A pull request should only contain one change. That does not mean only one commit, but one change - however many commits it took. The reason for this is that if you change X and Y but send a pull request for both at the same time, we might really want X but disagree with Y, meaning we cannot merge the request. Using the Git-Flow branching model you can create new branches for both of these features and send two requests.
