How can PHP scripts be updated automatically on multiple machines to ensure consistency and efficiency?

To update PHP scripts automatically on multiple machines, one solution is to use a version control system like Git. By hosting the PHP scripts in a central repository, changes can be pushed to all machines simultaneously. This ensures consistency and efficiency by keeping all instances of the scripts up-to-date.

// Sample PHP script to demonstrate automatic updating using Git

// Pull latest changes from the central repository
exec('git pull origin master');

// Additional code to execute after updating
// This can include restarting services or clearing caches
