Install the Latest PHP Version

sudo yum update
sudo yum install php7.x

Configure PHP Version

sudo alternatives --set php /usr/bin/php7.x

Enable Extensions

sudo yum install php-extension-module-list
sudo yum install php-extension-module-name

Verify Installation

php -v

Other Considerations

Choose the appropriate PHP version based on application compatibility.
If other PHP versions are installed, use alternatives --config php to switch between them.
When installing extensions, replace php-extension-module-list and php-extension-module-name with the desired extensions.
After upgrading PHP, you may need to restart the web server, such as Apache or Nginx, to apply changes.
