I operate a Wordpress web site, and my experience with PHP is limited to modifying Wordpress templates to achieve the HTML output I'm looking for.
I have a situation where my wordpress template is calling Yahoo Pipes to get a PHP array based on RSS aggregation to display on a page. Problem is, it takes about 7 seconds to load the page.
If I do this synchronously with the page load (which is all I've ever done), it seriously delays the page load.
What I would like to do is separate out the PHP call to Yahoo Pipes into another process - basically run it every 15 minutes or so, and generate an output file on my server. Then, I could include that output file in my PHP load of the home page for my site.
Does that make sense? Seems to me I should be able to do this using cron or something like that, but I've never run any PHP except via my wordpress install.
