StatusLib

This is a library designed to demonstrate an Apigility "Code-Connected" REST API, and has been written in parallel with the Apigility documentation.

It uses the following components:

• rhumsaa/uuid, a library for generating and validating UUIDs.
• zfcampus/zf-configuration, used for providing PHP files as one possible backend for reading/writing status messages.
• zendframework/zend-config for the actual configuration writer used by the zf-configuration module.
• zendframework/zend-db, used for providing a database table as a backend for reading/writing status messages.
• zendframework/zend-stdlib, specifically the Hydrator subcomponent, for casting data from arrays to objects, and for the ArrayUtils class, which provides advanced array merging capabilities.
• zendframework/zend-paginator for providing pagination.

It is written as a Zend Framework module, but could potentially be dropped into other applications; use the StatusLib\*Factory classes to see how dependencies might be injected.

Installation

Use Composer to install the library in your application:

If you are using this as part of a Zend Framework or Apigility application, you may need to enable the module in your config/application.config.php file, if you are not using the zend-component-installer:

Configuration

When used as a Zend Framework module, you may define the following configuration values in order to tell the library which adapter to use, and what options to pass to that adapter.

For purposes of the Apigility examples, we suggest the following:

• Create a PHP file in your application's data/ directory named statuslib.php that returns an array:

• Edit your application's config/autoload/local.php file to set the array_mapper_path configuration value to data/statuslib.php:

The above will provide the minimum necessary requirements for experimenting with the library in order to test an API.

Using a database

The file data/statuslib.sqlite.sql contains a SQLite schema. You can create a SQLite database using:

The schema can be either used directly by other databases, or easily modified to work with other databases.

StatusLib in a New Zend Framework Project

1. Create a new Zend Framework project from scratch; we'll use my-project as our project folder:

2. Install the StatusLib module:

3. Build a DataSource

   • Option A: Array data source:

     First, copy the sample array to the data directory of thet application:

     Then, configure this datasource by setting up a local.php configuration file:

     Next, add the StatusLib specific configuration for an array based data source:

   • Option B: Sqlite data source:

     First, create a sqlite3 database, and fill it with the sample data:

     Then, configure this datasource by setting up a local.php configuration file:

     Next, add the StatusLib specific configuration for a sqlite database based data source:

4. Create a test script to prove the data source is working:
