How can one configure the PHP version used by the web server?

To configure the PHP version used by the web server, you can typically do so by modifying the server's configuration file (such as php.ini or httpd.conf) to specify the desired PHP version. This can involve setting the appropriate PHP path or module for the web server to use. Additionally, you may need to restart the web server for the changes to take effect.

// Example of modifying the Apache server's configuration file (httpd.conf) to specify the PHP version
// Locate the line that loads the PHP module and update it to point to the desired PHP version
LoadModule php7_module /path/to/php7_module.so

// Restart the Apache server for the changes to take effect
