Webscraping is something that practically always has to be done custom for the very page you want to scrape. You need to adapt it to it specifically, and you need to cater for any changes that are made to the source website, continously. That's hard if you have no idea yourself, and its even harder in Perl (which every reasonable web dev has long forgotten). Are there no reliable xml sources for the stuff you want?

Anyway, Max is absolutely right - to do this in Perl is like trying to fix a car with a stone axe or write a book with stone and chisel. Still you were told how to call a perl script from php - we do know how to do that. What we don't know and can't know is the correct path and permissions setting on your server.
