Re: empty list removed

Hrm. Now I see your link but... https://i.imgur.com/43heo5B.png In "A variable is considered empty if it does not exist or if its value equals false" what about changing the words "equals false" to link to the page you mentioned? Also can we link from https://www.php.net/manual/en/types.comparisons.php to the boolean page somewhere? Thanks Karoly Negyesi On Mon, Jul 5, 2021 at 2:08 AM Christoph M.
