Install/enable sqlsrv & pdo_sqlsrv drivers for php8.1 on ubuntu20.0

I am trying to enable sqlsrv drivers for php8.1 on Ubuntu 20.0. It is not showing the extension in phpinfo().

When trying to check the sqlsrv module with commmand php -m, the output is like this:

I have followed official documentation below:

• https://learn.microsoft.com/en-us/sql/connect/php/installation-tutorial-linux-mac?view=sql-server-ver16
• Tried to add extension(extension=pdo_sqlsrv.so, extension=sqlsrv.so) in /etc/php/8.1/apache2/php.ini

I am not sure what went wrong, any suggestion is appreciated.

The output of phpinfo() for php7.4:

The output of phpinfo() for php8.1:

Here are the things:

• PHP 7.4 and 8.1 installed on my machine.
• The sqlsrv drivers works fine for php7.4 version
• When trying to install/enable for php8.1 it does not work at all.

What I am missing here?

You can try this:

1. switch to php8.1
2. sudo pecl uninstall -r sqlsrv 
3. sudo pecl uninstall -r pdo_sqlsrv 
4. sudo pecl -d php_suffix=7.2 install sqlsrv
5. sudo pecl -d php_suffix=7.2 install pdo_sqlsrv
6. sudo service apache2 restart

Note that -r, --register-only do not remove files but only register the packages as not installed.
