                                                 <option style='sort'> <?php echo $bankname ?> - <?php echo $bankifsc ?> </option>
                                                 <?php } ?>
                                               </select>

You can order by SQL, which will always be faster than sorting with PHP:

select * from bank_details order by bank_name ASC

This is AZ ordering

select * from bank_details order by bank_name DESC

This is ZA

You can also order by multiple columns if you'd like, just add each in a comma separated list just like your select column list:

select * from bank_details order by bank_name, city_name DESC

Note that this will order by city name descending (ZA) and bank_name by the default (AZ, or ascending). So, you can do:

select * from bank_details order by bank_name DESC, city_name DESC

Also, since there's a default, you can just do:

select * from bank_details order by bank_name
