How to pass data from controller to view in Laravel
Passing arrays using the view() helper function is the most common way, suitable for small and medium-sized data volumes; 2. Use the with() method to pass variables in chain or group, suitable for conditional addition of data; 3. When the variable name is the same as the view key name, using the compact() function can make the code more concise; 4. Use view()->share() to share data with all views, suitable for global data such as site name or number of users; 5. For complex logic, use ViewComposers to inject data into specific views such as sidebars or menus. Each method has its own applicable scenarios based on scope and complexity. The core is that the array key name will automatically change to the variable name in the Blade template, so that it will be directly in the view.
