问题 I am using CodeIgniter. I want to create an array to add to a dropdown which contains the numbers 1 -> 1000. I have tried the php range() function like so $arr = range(1,1000); It worked and create a dropdown from 1 to 1000. I do have one problem though. When select text 1 from my drop down and post, the posting value is 0 . Because by default the keys are starting from 0 and the key is set to the dropdown value Here is part of my drop down HTML <select id="user-day" class="dropdown-small
