Updating php on google cloud for wordpress installation Debian 4.9

I have been trying to update PHP on my install of WordPress on Google Cloud.
I have followed these instructions: How do I upgrade from PHP 7.0 to 7.3 on google cloud platform?.
When I do a php -v command, it shows that it is updated, but within WordPress it is still showing version 7.0, not the updated version.

    Your system appears to have two installations of PHP. One for the CLI and another Apache or you have not restarted Apache after the update. First restart Apache and recheck.

    The command to install Apache PHP is sudo apt install libapache2-mod-php7.3.

    Warning: Be careful with manual updates of PHP and other software that may have interdependencies. Make sure you have backed up your system (image) before so that you can recover is something goes wrong. Debian 4.9 is very old (obsolete) and might not be supported or even tested with the latest versions of third-party software.

    The Linux command where php will tell you where PHP is installed. To figure out if you have a different installation for Apache, create a new web page, such as myphpinfo.php with the following contents. Then use your browser to view the page:

    <?php

// Show all information, defaults to INFO_ALL
phpinfo();

?>

    Your browser will display a page like this:
