php How to make a right twitter api curl with oauth
You're using mktime incorrectly, it doesn't accept a date string. Instead of that however, I'd recommend that you do ...
$time = time() - 86400;With regards to your other questions, I recommend getting an oauth capable twitter library for PHP. There are plenty out there, and there's no point in reinventing the wheel ... usually :)

Also, check that you're time/date are properly set on your server. Twitter will throw an out of bounds error if your timestamp is off by more than ~24 hours.
