I am trying to create a drop-down box where the variables are pulled from a mysql table. The drop-down box is for cities that the client exists. The roblem that I am having is that there may be more than one entry of the same city if more than one client exists in the same city, but I only want one to appear in the drop-down box. How do I use PHP to only show one entry n the drop_down when multiple entries exist.
Avoiding multiple entries
