# Developers

The code is available from https://github.com/phpservermon/phpservermon. There is a master branch, which is stable and always reflects the latest release. The develop branch is used for ongoing development and should not be considered stable. If you would like to contribute a patch or feature, please fork the develop branch and send a pull request.

## Languages

The server monitor uses language files, which are stored in the directory “src/lang”. The name of the language file consists of the language code (ISO 639-1) and the country code (ISO 3166-1), separated by an underscore. The extension is ”.lang.php”.

### Locales

Each language file should contain a ‘locale’ key which can be used for formatting dates and times. This ‘locale’ key must include the locales for different server environments:

- Linux / OS X: same as filename (language code and country code separated by underscore)
- Windows: http://msdn.microsoft.com/en-US/library/39cwe7zf%28v=vs.80%29.aspx

For more information, see http://www.php.net/manual/en/function.setlocale.php

For display purposes, the language file should also provide the text direction (ltr / rtl) and language subtag. Unfortunately they do not match 1:1 with the locales used for the server. Valid language subtags can be found on http://www.iana.org/assignments/language-subtag-registry/language-subtag-registry.

### Adding a new language

To add a new language, follow these steps:

- Create a new file in the directory “src/lang” named “{locale}.lang.php”.
- Copy the contents of the file “en_US.lang.php” to your new file.
- Your new language should now be available on the config page.
- Translate :-)
- Please send a pull request on github (https://github.com/phpservermon/phpservermon) so it can be included in the next release :-)

## Getting started

### Vagrant

If you are not familiar with Vagrant, have a look at https://www.vagrantup.com/ for more information (it is awesome). To ease development, a Vagrantfile has been included along with a full provisioning profile generated using PuPHPet (https://puphpet.com). The Vagrantfile is configured to set up a CentOS 6.5 box with PHP 5.6 and MySQL installed, with a local port forward on port 8080. To set up the development environment, make sure you have Vagrant and VirtualBox (https://www.virtualbox.org/) installed, then run:

    vagrant up

The initial setup may take some time as the virtual machine needs to be provisioned. After that, you can access your development environment by navigating to http://localhost:8080/psm/ or http://192.158.56.101/psm/. The config.php file has been created automatically, but the first time you do need to run through the install wizard.

### Code

All code related to phpservermon lives in the “psm” namespace, which can be found under “src/psm”.

The Router (https://github.com/phpservermon/phpservermon/blob/develop/src/psm/Router.class.php) is used to load the modules. All modules are registered inside the Router class with a unique ID (see getModules()), and can either be loaded manually ($router->run(‘mod’)), or if no module is given it will attempt to discover the module from the $_GET[‘mod’] var. If no valid module or controller is found, it will fall back to the default module.

The module var may exist of 2 parts, separated by an underscore. The first part is the ID of the module, and the second part is the ID of the controller registered in the module. If no controller ID is found, it will attempt to load the controller with the same ID as the module.

Examples

    $router->run('config'); // module ID "config" and controller ID also "config" (same as $router->run('config_config'))
    $router->run('server_status'); // module ID "server" and controller ID "status"

If the user is not logged in and login is required, it will automatically load the user login controller without throwing an error.
