title: Return latitude/longitude based on entered address
body: <p>I'm building a php based application for a client to enter in addresses for their customers' buildings. They'd like the ability to view the location on a map (either as individuals or grouped in a city search).</p>
  
  <p>What I'm trying to accomplish is a lookup once the address is entered into a form that populates the database, so after they enter in the addresss, city, state, zip (these are all US locations) they could click a "get lat/long info" link/button that would check to make sure the data is complete, then would lookup the address and return the latitude/longitude into the appropriate form fields. Then the form could be submitted to store the info, and I could later just pull the lat/long when plotting on a map.</p>
  
  <ol>
  <li><p>Does this make sense, or would I be better off just doing the lookup when it's time to plot it?</p></li>
  <li><p>Does anyone have any pointers to solve this problem?</p></li>
  </ol>
  
  <p>I've seen some of the Google/Yahoo API's but it looks like this is more based on the plotting a point part. I may be able to modify it to suit my needs, but I'm just trying to cut some research time posting here with the hopes one of you may have a more direct route.</p>
  
  <p>I'll RTM if I have to...</p>
