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?
>Solution :
The test for "may not exist or may be falsey" is:
if (empty($option['type']))
