What happens when a cached view is updated in Laravel?

Consider a Laravel application where a view is cached using php artisan view:cache. If you update the blade template file after caching, what will the user see when accessing that view?

A The user sees the updated view immediately because Laravel automatically refreshes the cache.

B Laravel throws an error because the cached view does not match the updated blade file.

C The user continues to see the old cached view until the cache is cleared or rebuilt.

D The view is not cached at all if the blade file changes, so the user sees the updated view.

💡 Hint

Think about how caching works and when Laravel refreshes cached views.

Laravel stores compiled views in cache. If you update the blade file after caching, Laravel will still serve the cached compiled view until you clear or rebuild the cache.

Which command caches all blade views in Laravel?

Choose the correct artisan command that compiles and caches all blade views for faster rendering.

A php artisan cache:compile-views

B php artisan cache:views

C php artisan view:compile

D php artisan view:cache

💡 Hint

Look for the command that explicitly mentions 'view' and 'cache'.

The correct command to cache all blade views is php artisan view:cache. It compiles all blade templates and stores them for faster access.

Why does Laravel serve stale views after updating blade files?

After running php artisan view:cache, you update a blade file but the changes do not appear in the browser. Which of the following is the most likely cause?

A The view cache was not cleared, so Laravel serves the old compiled view.

B The blade file has syntax errors preventing recompilation.

C The web server cache is disabled, causing stale views.

D Laravel automatically detects changes and recompiles views, so this should not happen.

💡 Hint

Think about what happens to cached views when blade files change.

When views are cached, Laravel serves the compiled versions until the cache is cleared or rebuilt. Updating blade files alone does not refresh the cache.

How does Laravel's view caching improve performance?

Which explanation best describes how Laravel's view caching speeds up page rendering?

A It stores the raw blade templates in memory to avoid disk reads.

B It compiles blade templates into plain PHP code and stores them to avoid recompilation on each request.

C It caches the full HTML output of views to serve static pages instantly.

D It compresses blade files to reduce their size and speed up loading.

💡 Hint

Consider what happens when Laravel compiles blade templates.

Laravel compiles blade templates into plain PHP code and caches them. This avoids recompiling templates on every request, improving performance.

What is the output count of cached views after running view:cache on 3 blade files?

You have 3 blade files in your Laravel project: home.blade.php, about.blade.php, and contact.blade.php. After running php artisan view:cache, how many compiled view files will Laravel store in the cache directory?

A 3 compiled view files, one for each blade template.

B 1 compiled view file containing all 3 views combined.

C 0 files, because view:cache only caches routes, not views.

D Depends on how many views are rendered during runtime, not the blade files.

💡 Hint

Think about how Laravel compiles blade templates individually.

Laravel compiles each blade template separately and caches each as a compiled PHP file. So 3 blade files produce 3 cached compiled files.
