title: Change php variable value with jquery
body: <p>I have the following issue. I am building a form in which a user can select a value from a select option and i want to save that value into a php variable. The form and everything are in the same php file. Is there anyway to achieve something like that with jquery?</p>
  
  <p>I do not want to submit the form, just to change the value of php variable.</p>
  
  <p>Thanks</p>
