Run php script cronjob

[RobotFX]

I'm using wget to run some scripts without any problems, but I've complicated a little the script and I'd like to use this command:

wget -o /dev/null -O /dev/null - http://site.com/script-to-sent-email.php?feed=http://feeds.feedburner.com/myfeedaddress&email=[e-mail] >> /dev/null 2>&1

The script-to-sent-email.php is supposed to send a feed to an email box - it uses the GET command to get the feed and the email, as in the example. It works in the browser, but doesn't work with whet, php, lynx or curl commands, as a cron. I think there's something to do with the "?" or the "@" but I'm not sure.
Anyway, is there a way to run it like this or I shouldn't use GET and instead just put everything inside the script file (the email and the feed's address)? Btw, the second option works, I am, however, curious if I can make it work like the above, using the GET for the feed and email.
Thanks!
