title: $_POST responding back to webpage, and how to deal with data on a dynamic web page
body: <p>I am fairly new to php so this functionality stumps me, I'll give you a picture for context. <a href="http://i.stack.imgur.com/C7mnm.png" rel="nofollow">layout of application for reference image</a></p>
  
  <p>So I can query my data base and set each bit of data to an individual variable (<em>maybe not the best way for this situation?</em>)
  But I don't know how to $_post that data (<em>in variable form... :) probably bad idea, and I'll have to set the data as variables where ever I work with the formulas and only send information over ajax</em>) back to the displayed page (<em>note: I don't want my page to ever have to refresh</em>)
  And I foresee another problem, and its due to lack of knowledge and google failing to answer my questions, how can I have php Run my algorithms and keep the original data in the page every time my users change one field on the page, I want them to all run on the server and not in browser so I'm planing on having ajax send all the data including the changed data to a php file every time they change something and have it reset the information on the page after it runs its formulas. i have been studying $_post and get and request ect. and not been able to mentally layout how the transmission of data would be the most efficient and easiest to work with.</p>
  
  <p>Sorry for the ramble, I hope for some constructive criticism, solutions and explanations to a newbie at php and thank you for any and all help.</p>
