changing the node version used by apache web server

Question

Hi here are few observations, Click Here

I have a php program `

<?php
$op=exec('node -v');
$op1=exec('which node');
echo "Node  version : $op";
echo "\n Node path : $op1";
echo "\nUser : ". get_current_user();
?>

` when i run this program from my command line as ubuntu user

Node  version : v20.11.1
Node path : /home/ubuntu/.nvm/versions/node/v20.11.1/bin/node
User : root

when i run this program from command line as root user

Node  version : v18.20.0
Node path : /root/.nvm/versions/node/v18.20.0/bin/node
User : root

and when i run this file from browser

Node version : v10.19.0 
Node path : /usr/bin/node 
User : root

I want the node version used by apache web server also to be set to node 18 or node 20. How can i do that? as i want to use some node modules that are not compatible with node 10. How can i change node js version for apache web server to 18 or 20?
