Description of the bug

I can't seem to install to run on my local web server (which uses PHP 8.1.2)

Is there a way around this without me having to downgrade my version of PHP?

mPDF version

8

PHP Version and environment (server type, cli provider etc., enclosing libraries and their respective versions)

8.1.2

Reproducible PHP+CSS+HTML snippet suffering by the error

composer require mpdf/mpdf dev-php8-support gives me errors, and I guess the important part is:

Package mpdf/mpdf at version dev-php8-support has requirements incompatible with your PHP version, PHP extensions and Composer version:
...~8.0.0 which does not match your installed version 8.1.2...

Run just composer require mpdf/mpdf, why would you install dev-php8-support?

With that command, I'm getting version 6 something, and running into the curly braces issue.

Sorry for sticking this is issues at first - I wasn't sure which way to go with it...

[finwe]

You can try clearing composer caches and removing composer.lock first.

Or run composer require mpdf/mpdf "^8.2"

[finwe]

Also make sure you don't already have mpdf/mpdf with older version item in the composer.json

Thank you.
Is that command in a doc somewhere that I missed? I ask so I can dope slap myself if it was, and because now I'm having a Uncaught Error: Class "mPDF" not found in... error, but I know by reading some other docs and forum (Github and StackExchange) posts that calling mpdf has changed over time. I'm doing $mpdf = new \mPDF(); but think I read it used to be some variation (\mPDF\mPDF was one I saw)

[finwe]

Which command?

The class name has changed, but the other way around. Class \mPDF is for version 6.x, in 7+ it's namespaced and PSR-2 cased to \Mpdf\Mpdf.

Thanks @finwe- I'm making legit PDFs with proper filenames now. I've got another question/issue, but I'll start a different thread.
