Need help with file i/o 2

[clintcompute]

Hi,
I am trying to get an RSS interface set up on my server, and appear to have gotten everything working with magpie (

http://magpierss.sf.net)

and the unlimitedpenguins RSS box viewer (

http://www.infinitepenguins.net/rss/).

The only problem is, right now Magpie fetches the newsfeed (for example slashdot.org/slashdot.rdf) every time the page is accessed. However, Slashdot gets cranky if you access it more than once every 30 min. So, I would like to be able to copy the remote file

http://slashdot.org/slashdot.rdf

to a local file, and access that instead. How would I copy it?

Thanks much,

use fopen() (

http://www.php.net/manual/en/function.fopen.php)

with a URL to open a readable handle to the data the server provides.

use fopen() again to open a writeable file handle to a file on the filesystem.

Read from the first.

Write to the second.

Close both handles. Want the best answers? Ask the best questions:

Store the last time it was accessed (for eg, in a mySQL database) and check this each time the page is loaded, if it's over 30mins then do as above and write the new time to the database, otherwise use the copy

date last modified could be handy --BB

Don't really need that if you're fetching it every 30mins anyway
