I have an error in my PHP 7.3 and it refers to a line of code which is:
if (!is_int($Key) || $Key != $LastKey + 1)
The exact error is Warning: A non-numeric value encountered in /my/filename.php

care to share values of `$Key` and `$LastKey`? – Lawrence Cherone Apr 15 '20 at 16:13

Check what is `$LastKey` and `$Key` – u_mulder Apr 15 '20 at 16:13

Did this code run without an error in an earlier PHP version? Just wondering because you specified PHP 7.3. – Don't Panic Apr 15 '20 at 16:13

1It was 7.1 that introduced that warning for mathematical operations - the only bit of this code that would raise it is if `$LastKey` isn't numeric. See https://3v4l.org/csre0 – iainn Apr 15 '20 at 16:16
