PHP Configuration Loader Class

About

The PHP configuration loader class helps the management and loading of application configuration through arrays or Yaml configuration files.

Installation

Via Composer:

composer require am/config

Or simply download the code and add to your project.

Example Use

config.yaml

root_path: C:/xampp/htdocs
base_url: /
directories:
  controllers: controllers
  models: models
  views: views
  core: core
test_number: 10

config-2.yaml

this name: config 2
this number: 10
test_number: 10

<?php
require dirname(__DIR__) . '/vendor/autoload.php';

$config_mixed_src = array(
	dirname(__DIR__) . '/examples/configs/config.yaml',
	dirname(__DIR__) . '/examples/configs/config-2.yaml',
	array(
		'hotel'=>'5 star',
		'rooms'=> 10
	)
);
$config = new \Am\Config\Config($config_mixed_src,1,true);

var_dump($config);

Resulting dump:

<?php
object(Am\Config\Config)[2]
  public 'config' => 
    array (size=3)
      0 => string 'C:\xampp\htdocs\projects\composer\config/examples/configs/config.yaml' (length=69)
      1 => string 'C:\xampp\htdocs\projects\composer\config/examples/configs/config-2.yaml' (length=71)
      2 => 
        array (size=2)
          'hotel' => string '5 star' (length=6)
          'rooms' => int 10
  public 'src' => int 1
  public 'debug' => boolean true
  public 'root_path' => string 'C:/xampp/htdocs' (length=15)
  public 'base_url' => string '/' (length=1)
  public 'directories' => 
    array (size=4)
      'controllers' => string 'controllers' (length=11)
      'models' => string 'models' (length=6)
      'views' => string 'views' (length=5)
      'core' => string 'core' (length=4)
  public 'test_number' => int 10
  public 'this_name' => string 'config 2' (length=8)
  public 'this_number' => int 10
  public 'hotel' => string '5 star' (length=6)
  public 'rooms' => int 10

You can now retrieve application configuration within your file as public vars as follows:

echo $config->hotel; //returns "5 star"

foreach($config->directories as $dir){
	echo $dir;
}
