Helper file in very useful to create custom helper functions in Laravel app. We can use these custom helper functions app-wide.
First create the file
Then either load this file in any of the core Laravel file that autoloads when the application starts. Like,
require app_path() . '/helpers.php';
OR, change your composer.json file and dump the autoloader.
Then Run: composer dump-auto or composer dump-autoload
In this part, we will start learning how to target the browser. The browser gives us a hierarchy of objects, at the very top of this hierarchy is the “window” object.
We already know about the functional scope and the global scope. Anything global can be accessed from the entire code block. But, anything inside the functional scope can only be accessed within that function.
A virtual host can point to any folder on any drive of the system, it’s generally used to easily manage if we store all of our sites in a common location (like HTDOCS folder in case of XAMPP).
Virtual host also enables us to use “Preety URL” in our local development environment. Like:
We can Use: http://laravel.dev
Instead of: http://localhost/laravel5-test/public/
In short, virtual host enables us to point any directory or sub-directory by using our given (i.e. custom) URL format.
This part is a bit theoretical just like immediate previous lesson.
The loop actually means repeating codes. We can loop through any part of code as many times as we need to. Loops allow us to repeat code based upon a condition or a set of conditions. As long as the given condition is true, the loop will continue to repeat the same code over and over again. We can easily deal with arrays or big set of data through the loop.
Okay, I’m back in this series after a break! Good to have you till this mark!
Most important things in writing software are making decisions. Decisions allows us to add intelligence in our software. Basically decision means, if certain criteria happen – then we want to do something. Otherwise, we might want to do something else. We can make our programs make decisions by writing conditional statements.
We need to know about some operators before proceeding in depth of conditional statements.
