title: PHP To Add Multiple Values In One Entry Field
body: <p>I am creating a very basic photo uploading site that will allow users to:
  1) select a file to upload
  2) choose an category from a drop down
  3) tag the photo with names</p>
  
  <p>Users will then be able to search using their name to find pictures.</p>
  
  <p>Since there will be situations where the uploading user will want to tag multiple people who appear in a single photo, is there a simple way to allow them to type names separated by commas and then have PHP create unique entries in the database? If not, what's the best procedure for having multiple text fields to accomplish this?</p>
  
  <p>Thanks
