Mythweb PHP 7.4 Error - Creating default object from empty value

[Steve Tremayne]

Discussed in the forum: ​https://forum.mythtv.org/viewtopic.php?f=36&t=3553

MythTV 30.0 running on Arch Linux

Basically, upgrading PHP to 7.4 produced a lot of errors on the MythWeb page:

It seems like the following error is shown for every TV channel on the TV Schedule (Listings) page:

Warning at /var/lib/mythtv/mythweb/modules/tv/includes/programs.php, line 204:
!!NoTrans: Creating default object from empty value!!

(In my case, this was ~100 times, so several pages were just error messages)

Patch shown in forum post appears to resolve this issue:
