How do I update this?

[AngeloVilllasanta]

I've got a project and I've recently upgraded the PHP version to v8.3, and now I'm getting deprecated errors.

It's been a while since I downloaded and installed this using composer, and now I'm not sure how I update this. Is there a guide anywhere that I can follow? Thank you.

I think you will just have to collect the deprecation messages and change your code to eliminate them. It usually isn't terribly difficult. If you have particular messages that you can't figure out, post them here.

Php no longer offers any support, including security patches, for Php8.1. You can start by migrating there, but then you should repeat the process for 8.2, 8.3, 8.4, and 8.5.

Thank you for the quick answer, just a small self-correction, I am using PHP 8.3. I checked the error messages and they're mostly from the phpspreadsheet library, since I'm using an older version.

Here's an example of the logs:

Deprecated : Function libxml_disable_entity_loader() is deprecated in /Applications/MAMP/htdocs/my_project_folder/my_project/data/file_upload/parsers/vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Reader/Security/XmlScanner.php on line 67

So I think like I have to upgrade the library first....? Or am I going about this the wrong way?

It sounds like you are using a very old version of PhpSpreadsheet. None of our currently supported versions call libxml_disable_entity_loader for any Php release 8.0 or above. You need to fetch a fresh copy of PhpSpreadsheet.
