Variablen in Config.php ändern?

Hmm, hab hier mal was hingeschmiert... Funktioniert, könnte man aber sich noch verbessern.

PHP: 
<?php
class TextConfig extends ArrayObject
{
	private $config = array();
	private $file;
	
	public function __construct()
	{

	}

	public function loadConfig($file)
	{
		$this->file = $file;
		$config = include($file);
		$this->config = unserialize($config);
	}
	
	public function saveConfig($file = null)
	{
		if(!$file)
			$file = $this->file;
		$config = "<?php\n return '";
		$config .= serialize($this->config);
		$config .= "'; \n?>";
		file_put_contents($file, $config);
	}
	
	public function offsetSet($index, $newval)
	{
		$this->config[$index] = $newval;
	}
	
	public function offsetGet($index)
	{
		return $this->config[$index];
	}
	
	public function debugMe()
	{
		print_r($this->config);
	}
}

?>
 
Guten Abend!
So bin wieder am heimischen PC! Also ich habe mich lange mit diesem Thema beschäftigt und habe mir ehrlich gesagt sehr lange die Zähne an einer Lösung mit parse_ini_file() ausgebissen. Dann bin ich auf die Methode mit dem Array in einer Datei gestoßen. Das stellte sich anfangs sehr leicht da. Endlich eine Klasse, die man einfach so runtertippen kann, doch dann kam ich ans speichern. Eine Lösung dafür hatte ich zwar, allerdings muss ich gestehen, dass diese nicht wirklich akzeptabel war. Dank Felix Jakobi konnte ich das Speichern und Einlesen nun stark optimieren. Kannte die Funktionen unserialize() und serialize() leider nicht. Eigentlich hatte ich noch eine Fehlermeldung in die __set()-Methode eingebaut, doch habe ich die rausgenommen, da es mir so möglich wird auch neue Einträge in die Konfigurations-Datei vorzunehemen, da zum Beispiel ein neues Modul installiert wurde. Habe mal einen Beispielaufruf unten an die Datei gehängt.
MfG, Andy

Hallo zusammen!
Mich hat etwas an der ersten Config-Klasse gestört. Man konnte nicht wirklich in der Konfigurations-Datei selbst erstmal Handanlegen und zudem gab es keine Kategorisierung der Daten. Daher habe ich eine neue Klasse geschrieben. Leider muss ich sagen, dass ich diese nicht wirklich ausreichend getestet habe, da ich momentan leider unter akuter Müdigkeit leide (man beachte die Uhrzeit). Trotzdem würde ich mir wünschen, dass vielleicht der eine oder ander mal einen Blick auf die Klasse wirft und verbesserungsvorschläge (speziel zur methode save()) macht. Freu mich natürlich auch über jeden tester.
MfG, Andy
