If don’t want to install any extensions Run the following command to install PHP 8.1 only:

sudo apt install php8.2

Step 4: Verify PHP Installation

To verify that PHP 8.2:

php -v

If everything has been installed correctly, you should see the following output:

PHP 8.2.x (cli) (built: DATE) (NTS)

Step 5: Check installed extensions

Note: before doing this make sure you have installed Apache.

To view the list of installed extensions, you can create a PHP info file by following these steps

Create a new file called info.php in your web server’s root directory:

sudo nano /var/www/html/info.php

Note: If you’re using a different web server, the root directory may be different.

Add the following code to the info.php file:

<?php
phpinfo();
?>

Save the file and exit the text editor.

Open a web browser and navigate to http://your-server-ip/info.php. You should see a page with detailed information about the PHP installation, including a list of installed extensions.

If you’re using a firewall, make sure to allow inbound traffic on port 80 (HTTP) to access the PHP info page.

Once you’re done checking the installed extensions, you can remove the info.php file from your server to avoid exposing sensitive information.

rm /var/www/html/info.php
