How can PHP developers effectively maintain the accuracy and relevance of their documentation over time?

PHP developers can effectively maintain the accuracy and relevance of their documentation over time by regularly updating it to reflect any changes in the codebase, using version control systems to track changes, and encouraging collaboration among team members to ensure all information is up-to-date. ``` // Example PHP code snippet demonstrating the use of version control for documentation maintenance // Step 1: Initialize a Git repository for the project // Run this command in the project directory // git init // Step 2: Create a new branch for documentation updates // git checkout -b documentation_updates // Step 3: Make changes to the documentation files // Update relevant sections with accurate and up-to-date information // Step 4: Commit the changes to the repository // git add . // git commit -m "Update documentation for accuracy" // Step 5: Push the changes to the remote repository // git push origin documentation_updates // Step 6: Merge the documentation updates branch into the main branch // git checkout main // git merge documentation_updates ```
