nargy | Ok, je te file le code que j'utilise. Je le metes dans le fichier rss.inc, que j'inclue quand j'en ai besoin avec include("~/phplib/rss.inc" ).
rss.inc:
Code :

Il y a deux affichages différents, tous deux en javascript. L'un affiche avec un défilement de caractères, l'autre est plus joli.
Après avoir inclu rss.inc, tu utilise donc l'une des deux fonctions:
show_rss($title,$file,$width, $delay)
show_rss2($title,$file,$width, $delay)
- $title: titre à afficher , par exemple: 'news portables:'
- $file: flux rss. normalement tu indique ici un nom de fichier, mais si tu n'a pas trop de traffic sur ton site, tu peut indiquer l'adresse web (http://...bestofmicro.....).
- $width: taille en caractères pour show_rss (par ex. 50), taille CSS pour show_rss2() (en pourcentage '80%', en pixels '400px', en caractères '30ex')
- $delay: intervalle de défilement, en millisecondes, essaye des valeurs proches de 100.
