i have written some php code -- about 400 lines -- that allows me to pull data off particular websites (nothing too naughty; it's public financial data from the central bank).
the php code takes up to 60 seconds to finish execution, mainly because it pulls data down from about 4 rather slow sites.
the code finally produces a small HTML file comprising collected data that is imported and displayed in a side bar custom island.
my issue is this: i wish to run this code about every 30 minutes to keep my site up to date with local financial data. where should i place this code? can i call it from the body section of the custom islands? and if i do, will there be any speed consequences for my users?
i'd be thankful for anyone's thoughts on this.
