Hi,
urls wie http://domain.com/index.php?page=home geltens als nicht suchmaschinenfreundlich, bieten jedoch den Vorteil daß man leicht mit $_GET auf die Parameter zugreifen kann. Möchte man eine suchmaschinenfreundliche url kann man mit Segmenten arbeiten, die url sieht dann so aus: http://domain.com/index.php/home/
Man kann es zwar mittels .htaccess umd mod_rewrite machen, aber es funktioniert bei manchen kostenlosen Hostingpaketen nicht.
Mir geht es um eine Lösung die nur mit PHP auskommt. Mein erster Ansatz ist:
index.php
PHP
