Question

If my drop down has 10 options to select from, and option 4 is selected, how can I write the code to select an option from 1-10 exluding 4?

I know rand(1, 10) picks a random number from 1 to 10, but it sometimes can land on 4. How can I make sure that it doesn’t pick the number 4, or any number that is already selected?

What about something like that?

<?php

$filtered_key = 4;

$range = range(1, 10);
unset($range[$filtered_key]);
$key = array_rand($range);

echo $key;
