PHP8 deprecated function warnings

Patch with the proposed modifications.

Reviewed the code of #2 patch and tested the patch locally. it is working perfect.
Moving to RTBC.

I'm seeing a further PHP8.1 deprecation in views_pdf_template.php:

Deprecated function: Automatic conversion of false to array is deprecated in PdfTemplate->addPage() (line 988 of /var/www/html/d7-dev.localhost/sites/all/modules/views_pdf/views_pdf_template.php).

Should we address that one here also, or shall I create a separate issue?

@stevewilson could you please add it in here, really appreciate it.

Can try to build a new tag this week with several PHP related issues and fixes.

@killua99 - I've added this new deprecation to the Issue summary - I hope that's what you wanted.
If you need any further information please let me know.
Changed Status to "Needs work" as the existing patch doesn't cover this latest deprecation and I don't feel confident to provide a fix for it.

thank you @SteveWilson

Created an MR !5 with changes shared in #2 patch and also addressed the warnings shared in #5.
(Please not: unassigning the issue from the reporter as it has been over 6 months.)

Please review, thanks!

Thank you @ankithashetty. I've manually incorporated your MR !5 changes into my test site and I'm no longer seeing the deprecation reported at comment #5 🐛 PHP8 deprecated function warnings Needs review . Given that the patch at #2 🐛 PHP8 deprecated function warnings Needs review was previously RTBCed for the deprecations reported originally, it seems safe now to set this issue back to RTBC - done.

I should perhaps add that I was also seeing PHP8.1 deprecations reported by TCPDF - I was using version 6.3.2. I've since updated to the latest version (6.6.5) and everything seems to be fine now.

thanks going to update versions of libraries as well

I've added a further deprecation to the Issue summary - as seen with PHP 8.2.
