I'm currently working through a large number of warnings I have logged after my server was updated to PHP 8.
One particular point that has me scratching my head is the following code block
if (!$option['type'] || $option['type'] == "select") {
$output .= '<b>'.$option['title'].':</b>';
}
I know that I can use isset($option['type']) like this
isset($option['type']) && $option['type'] == "select"
but confused how that would work for
!$option['type']
How can you be checking if isset, but also it being NOT. If it's NOT, then surely it isn't set anyway?
The test for "may not exist or may be falsey" is:
if (empty($option['type']))
