How to generate dynamic selectbox with optgroup

Question

Hi I am having this mysql table.

CREATE TABLE IF NOT EXISTS `selling_counties` (
  `county_id` int(11) NOT NULL auto_increment,
  `country` varchar(20) collate u         


        

Answer 1

Create a new array like this, with countries as the keys, and the array of counties as each value. Assuming $rows is the array of raw table rows.

     $counties): ?>
