How can PHP developers efficiently manage and update scripts across multiple servers or websites?

Managing and updating PHP scripts across multiple servers or websites can be efficiently done by using version control systems like Git. By creating a central repository for the scripts and using branches for different servers or websites, developers can easily manage changes and updates. Additionally, automation tools like Jenkins can be used to deploy changes to multiple servers simultaneously.

// Example PHP script to update multiple servers using Git and Jenkins

// Connect to the central Git repository
$repo = git::open('/path/to/central/repository');

// Pull the latest changes from the repository
$repo->pull();

// Deploy changes to multiple servers using Jenkins
$jenkins = new Jenkins('http://jenkins-server-url');
$jenkins->build('deploy-script');
