Here's a simple settings class that parses an ini file for settings. It has a private
constructor so that it can only be instantiated through the getInstance method, this means that
there can only ever be one settings object at a time.
<?php
class Settings {
private static $instance;
private $settings;
private function __construct($ini_file) {
$this->settings = parse_ini_file($ini_file, true);
}
public static function getInstance($ini_file) {
if(! isset(self::$instance)) {
self::$instance = new Settings($ini_file);
}
return self::$instance;
}
public function __get($setting) {
if(array_key_exists($setting, $this->settings)) {
return $this->settings[$setting];
} else {
foreach($this->settings as $section) {
if(array_key_exists($setting, $section)) {
return $section[$setting];
}
}
}
}
}
?>
settings.ini
[General]
url = "http://www.example.com"
[Database]
host = localhost
username = user
password = password
db = cms
adapter = mysqli
Using the class
<?php
$settings = Settings::getInstance(/*path to settings.ini*/);
echo $settings->url;
print_r($settings->Database);
echo $settings->db;
?>
Output would be:
http://www.example.com
Array
(
[host] => localhost
[username] => user
[password] => password
[db] => cms
[adapter] => mysqli
)
cms
