title: Is there a way to find out HTTP Post parameter names when you don't have the form?
body: <p>There is a php web page that i want to submit my POST request but i don't know the name of the parameter. Is there a way to find out the name of the parameter that i should submit my values into.</p>
  
  <p>Update: I don't have the form that submit to that page. So i can't use $_POST.</p>
