----

PHP's processing of POSTs can read multiple input tags with the same name and turn them into an array, but you need to add "[]" to the name.  For example,  don't do this, 

   <input name="color" value="red">
   <input name="color" value="blue">
   <input name="color" value="green">

because only the last value will be kept, like this

   $_POST["color"] = "green"

Instead, do this

   <input name="color[]" value="red">
   <input name="color[]" value="blue">
   <input name="color[]" value="green">

This will give you an array of all the values,

   $_POST["color"] = array("red","blue","green");

(Tested with PHP 5.3.3)
