How can relative paths and version control systems help in managing website development?

Relative paths and version control systems can help in managing website development by providing a way to easily track changes and collaborate with team members. Relative paths allow for more flexibility when referencing files within a project, making it easier to move files around without breaking links. Version control systems like Git help track changes, revert to previous versions, and merge changes made by different team members.

// Example of using relative paths in PHP
include('../includes/header.php');
```

```php
// Example of using Git version control in PHP project
// Initialize a new Git repository
$ git init

// Add files to staging area
$ git add .

// Commit changes
$ git commit -m "Initial commit"
