any ideas? i dunno why i'm getting errors

Looks like you need to set the cURL option CURLOPT_RETURNTRANSFER to true.

curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);

http://php.net/curl_setopt

Default behavior is for curl_exec() to output data directly. By turning on that option, it returns the data as a string instead, which appears to be what you're expecting.
