PHP 8.2 not working

[RigidCollision]

I am running back to back PHP8.0 and PHP8.2 and am getting the following in PHP8.2:

Got the following email communication from Epic2022:

The deprecated functions mentioned in the warnings are related to the TCPDF library, which is used for generating PDF files.
The library has functions with optional parameters that are declared before the required parameters, which is not a good practice.
You should update your code to use the latest version of TCPDF or update the deprecated function calls. If you can't update the library or code, you can suppress the warnings by modifying your php.ini file or adding the following line of code to the top of your PHP file:
error_reporting(E_ALL ^ E_DEPRECATED);
This will turn off the deprecation warnings for the code that you are running. However, this is not recommended as the code may become unusable in future versions of PHP.
It's always a good practice to update your code and libraries to their latest versions to avoid such issues.

I will be taking a look at this and when I have a solution will be posting.

I am also stuck waiting on this issue

[aydos-t]

for ex.
$unicode = self::UTF8StringToArray($str, $isunicode, $currentfont); //don't work
Here you have to change the place of the variables:
$unicode = self::UTF8StringToArray($str, $currentfont, $isunicode); //workable way
or the variable $currentfont should write first:
$unicode = self::UTF8StringToArray($currentfont, $str, $isunicode); //workable way

In the end what I have done is get the latest FPDI and FPDF libraries and just re-work the original PHPMerger library to use them. Literally two lines need modifying that are specific to TCPDF (you remove the two lines specifically calling the TCPDF header and footer initialisation).

It works with PHPv8.3.3 and if you buy the official FPDI-Parser will handle pretty much everything. Even without the additional commercial parser it is as robust as the original.

This is pretty much what @johnloydlao has mentioned in the link above. When I drilled into what it was doing the code is really simple.

I am using:
FPDF v1.86
FPDI v2.6.0
FPDI-Parser v2.1.2 (not required but for (€100 probably worth it for robustness in a commercial environment).

There looks to be a new version of TCPDF under development which will handle some of the major changes brought about by PHPv8+. Information can be found here (https://tcpdf.org/ )but the link to the new version is: https://github.com/tecnickcom/tc-lib-pdf
A new TCPDF will remove the need for the additional FPDI-Parser (I believe) for dealing with PDF's version 1.4 and above.
