Hello, I would like to ask a question, I have an application that I made in 2018 in PHP 7.4.3 and I would like to update its version to the most current one. So I would like to know how I can do it? What changes do I have to make in the code?

Firstly, you will need to check if your current codebase is compatible with PHP 8. You can use tools like PHPCompatibility to check it.
Other than that, it depends really on what your code is and how much a difference there is between the requirements of 7.4 and 8.1, for example. Without seeing the code it's hard to say.

First check your version with php -v. Then, update it using your system’s package manager:

- Ubuntu/Debian: sudo apt update && sudo apt install php
- CentOS/Fedora: sudo dnf install php
- Windows: Download the latest PHP version from php.net, extract it, and update your system’s PATH.

After updating, verify with php -v and restart your web server (sudo systemctl restart apache2 or nginx). Let me know if you need help with specific configurations!
