Pretty Simple PHP Question

I need a way to take the entire content of a certain webpage and save it every 30 minutes. So I guess the best way to do it would be by running a cronjob every 30 minutes that uses file_get_contents() and writes the contents to a txt file right?

Also is there a way to save the source code as well?

I'm not sure, but you could probably use fread to read all the contents then fwrite to write them into another file. :)

I'm pretty sure you'd need to use a CRON job if you want to run it so often automaticly, can I ask why you want to do this? I always it a lot easier to help somebody when I understand what they want to do and why they want to do it. :)
