Installation/Usage

If you're using Composer to manage dependencies, you can include the following in your composer.json file:

"require": {
    "xiidea/ez-maintenance": "dev-master"
}

Then, after running composer update or php composer.phar update, you can load the class using Composer's autoloading:

require 'vendor/autoload.php';

Otherwise, you can simply require the given autoload.php file:

require_once 'PATH_TO_LIBRARY/autoload.php';

Then you can just call EzMaintenance\Worker::watch() In your index.php (see the example)

Different Adapters to check maintenance mode

Use adapter to detect if we need to serve the maintenance page or not. 3 Types of adapter provided. You can also define your own adapter.

File Adapters

This is the default adapter. it checks for a specific file if exist or not. default path is down. For the following implementation you will be shown maintenance page if there is a file exists named maintenance.enable

<?php

EzMaintenance\Worker::watch('file', array(
        'path' => 'maintenance.enable'
));

Env Adapters

Using this adapter you can watch over existence of an environment variable. The maintenance page will be shown if the environment variable is present with specific value.

<?php

EzMaintenance\Worker::watch('env', array(
        'var_name' => 'APPLICATION_ENV',
        'check_value' => 'down'
));

Const Adapters

This is same ad the env adapter. Only difference is it will check for a php constant instead of environment variable.

<?php

EzMaintenance\Worker::watch('const', array(
        'var_name' => 'APPLICATION_ENV',
        'check_value' => 'down'
));

Custom Adapters

You can define your own adapter by implementing the EzMaintenance\Adapter\AdapterInterface
