Getting Started

Good software development follows many patterns and architectures. We design things that depends on many other parts. Some of them are well structured Objects but many times we need to have some configurations. Often we use array as our config host but it can produce mass of unexpected side-effects becasue of one reason - array is not an Object so it can't follow any schema. But what if it can...

During my work I developed a simple wrapper tool that helped me with schema sensitive arrays and I decided to make it a package. I hope you enjoy it!

Installation

To install through composer, simply put the following in your composer.json file and run composer update

Or use the following command

Usage

Let's move to a Schema class. It's a validation tool with one interface method:

• $insert - This is your array that is a subject of validation
• $throw - This option change behavior of validation

By default check method throws an InvalidArgumentException when $insert doesn't follow schema.

Step One

Create your Schema array:

Available rules:

• required - given key must not be empty
• nullable - given key can be null
• boolean - given key must be boolean type
• float - given key must be float type
• integer - given key must be integer type
• string - given key must be string and can't be other types

Step Two

Create new instance of Mrluke\Configuration\Schema:

Note! From v1.2.0 you can create Schema by static method createFromFile(string $path, bool $json = false).

Step Three

Create new instance of Mrluke\Configuration\Host with Schema as a dependency and your $configArray is automatically validated.

If your $configArray doesn't follow given Schema, you will get InvalidArgumentException. You can also use Host without any Schema due to it's optional parameter of Mrluke\Configuration\Host.

Your configuration is Wrapped!

Now you have an access to Host methods:

Your key can follow dot notation to access nested keys:

By default if key is not present, Host returns null. You can also use magic getter to acces config:

You can check if given hey is present:

Plans

Feel free to contribute because I am aware that there are some things to improve. For now:

• Nested Schema support
• New validation rules support
• New Schema's file format
