There are many many amazing libraries in the PHP community and with the creation and adoption of the PSRs we don't necessarily need to rely on full stack frameworks to create a complex and well designed software. Choosing which components to use and plugging them together can sometimes be a little challenging. The goal of this set of packages is to make it easier to do that (without compromising the quality), allowing you to focus on the behaviour of your software. This particular package provides **abstractions** and **default components**to standardise some basic concepts, creating a foundation to connect different libraries together without creating a huge monster. Installation ------------ [](#installation) You probably won't depend directly on this package, but it is available on [Packagist](http://packagist.org/packages/chimera/foundation), and can be installed using [Composer](http://getcomposer.org): ``` $ composer require chimera/foundation ``` ### PHP Configuration [](#php-configuration) In order to make sure that we're dealing with the correct data, we're using `assert()`, which is a very interesting feature in PHP but not often used. The nice thing about `assert()` is that we can (and should) disable it in production mode so that we don't have useless statements. So, for production mode, we recommend you to set `zend.assertions` to `-1` in your `php.ini`. For development, you should leave `zend.assertions` as `1` and set `assert.exception` to `1`, which will make PHP throw an [`AssertionError`](https://secure.php.net/manual/en/class.assertionerror.php)when things go wrong.
