How can version control systems like Github be beneficial for collaborative PHP projects?

Version control systems like Github can be beneficial for collaborative PHP projects by allowing multiple developers to work on the same codebase simultaneously without conflicts. It provides a centralized location for storing and managing code changes, making it easier to track modifications, revert to previous versions, and merge changes from different contributors. Additionally, Github offers features like pull requests, code reviews, and issue tracking to streamline collaboration and ensure code quality.

// Example PHP code snippet demonstrating the use of Github for version control in a collaborative project

// Connect to Github repository
$repository = "https://github.com/username/repository.git";
$local_directory = "/path/to/local/directory";
exec("git clone $repository $local_directory");

// Make changes to PHP files
$file_path = "$local_directory/example.php";
$file_content = file_get_contents($file_path);
$file_content .= "\n// Add new functionality";
file_put_contents($file_path, $file_content);

// Commit changes to Github
exec("git add .");
exec("git commit -m 'Added new functionality'");
exec("git push origin master");
