 ... funciones.
Para no complicarse la vida, podrías crear un array con las URL a los XML y poner el parseo dentro de un foreach() ...

Prueba con esto: Código PHP: <?php
/* PHP RSS Reader v1.1

Free to use, please acknowledge me
Place the URL of an RSS feed in the $file variable.
The $rss_channel array will be filled with data from the feed,
every RSS feed is different by by and large it should contain:
Array {
[TITLE] = feed title
[DESCRIPTION] = feed description
[LINK] = link to their website
[IMAGE] = Array {
[url] = url of image
[DESCRIPTION] = alt text of image
}
[ITEMS] = Array {
[0] = Array {
[TITLE] = item title
[DESCRIPTION] = item description
[LINK = a link to the story
}
.
.
.
}
}
By default it retrives the Reuters Oddly Enough RSS feed. The data is put into the array
structure so you can format the information as you see fit.

?> y lo emplearías así: Código PHP: <?
$files[]= "http://www.forosdelweb.com/index.xml";
$files[]= "http://newsrss.bbc.co.uk/rss/spanish/news/rss.xml";
$files[]= "http://rss.news.yahoo.com/rss/topstories";
include("parser.php");
?> ... ve que se intentó hacer las modificaciones mínimas. Parece que sirve...  |
