exec() function giving me fits

Yesterday I could do this (all on one line); exec("curl -d \"name=myname&password=mypassword&btnsubmit=submit\" -s -o cdrlist.html https://theserver.com/list.html"); This is the one that worked, not the other one with the variables. Now this one does not work and I don't insert any variables into it. I have looked at exec(), shell_exec(), etc. trying to get something to work here, but crap. Anybody come up against this before? Maybe I should just go home... Thanks! Jay
