I'm new to PHP and this may be a stupid question to ask, so don't vote me down just because I don't understand something...
php -r "print_r(simplexml_load_file('http://twitter.com/statuses/user_timeline/31139114.rss'));"
let's take this for an example, by running this command i get (on screen) XML output.
my question is it possible to save this data instead of just screen but in a file and then read that file and have exact same as if you've have made that simplexml_load_file()
You can download the data, using something like file_get_contents ; it'll get you the whole XML in a single PHP string.
For instance :
$xml = file_get_contents('http://twitter.com/statuses/user_timeline/31139114.rss');
$xml now contains the XML string.
Then, you can write that string to a file, using file_put_contents.
For instance :
file_put_contents('/home/squale/developpement/tests/temp/test.xml', $xml);
And, to check the file, from the command-line :
$ cat test.xml
<?xml version="1.0" encoding="UTF-8"?>
<rss xmlns:atom="http://www.w3.org/2005/Atom" version="2.0">

<atom:link type="application/rss+xml" href="http://twitter.com/statuses/user_timeline/31139114.rss" rel="self"/>

After that, you can use simplexml_load_file to read from that file.
For instance :
$data = file_get_contents('/home/squale/developpement/tests/temp/test.xml');
And $data now contains your XML string ;-)
Considering the XML you get from the remote server is a string, no need to serialize it ; and file_put_contents is easier that fopen+fwrite+fclose ;-)
