  <p>I know this question has probably been asked many times, I've researched a lot and I need help with specific thing.</p>
  
  <p>Lets say I have a form and user enters longitude and latitude, and I have a database which has table containing longitudes and latitudes, how would I search for a point or points in that table that are within 15 miles of radius?</p>
