- 3. 3 Passing data is process of how we can take variable data, and pass it to our views to be rendered in the Browser.
- 4. 4 Laravel provides different ways to pass data to a view. We can pass data directly from routes or through the controller • Using view() • Using with() • Using compact() • Using Controller Class
- 5. We can directly pass the data in the ‘view()’ helper function by using the second parameter in the function which takes an array as key and value pair In view(), the first parameter is the name of the view and the second parameter is where we have specified one key and multiple values of the data.5
- 6. The ‘with()’ is a method to pass individual form of data and is used with the ‘view’ helper function As you can see in the above code, we have to specify an arrow ‘->’ and then use the ‘with()’ method with ‘view()’ helper function. And we can specify one or more ‘with()’ depending on the requirement and use case. 6
- 7. The ‘compact()’ is a PHP function that can be used for creating an array with variable and there value. Here the name on the variable is the key and the variable content is the value In view(), the first parameter is the name of the view and second is where we have to specify the ‘compact()’ function. 7
- 8. Passing data using controller class is easy and is the right way In above function, we saw that we make use of the view() function. It’s first argument is a string which specifies which view file to load. The second argument to view() is an array which holds dynamic data that we can pass to the view file. 8
- 9. HTTP works as a request-response protocol between a client and server. Example: A client (browser) sends an HTTP request to the server; then the server returns a response to the client. The response contains status information about the request and may also contain the requested content. So, request is what the client asks for the server to fulfill 9

- 11. To obtain an instance of the current HTTP request via dependency injection, you should type-hint the IlluminateHttpRequest class on your controller method. 11
