title: Send cUrl data without vars array
body: <p>I try to post data without setting variable or array. I don't know it's possible ?
  When i send $data = array('var_name'=>'var_val') everything works fine, but when i set $data ='to send' i don't get any post data. </p>
  
  <p>$data = 'sample data to send';</p>
