HTTP vs HTTPS HTTP (HyperText Transfer Protocol) is the most basic and known protocol (a standard set of rules) used to transfer data from a web server to a browser. It allows communication between different systems. HTTPS is HTTP with encryption i.e it uses encryption (TLS/SSL) to make HTTP requests more secure while transferring the data from a web server to a browser or vice-versa.  So there are benefits of using HTTPS for your website: 1. It makes your website more secure against data theft. 2. It also improves your SEO rank. So now let's learn how we can direct a website from HTTP to HTTPS. First, make sure you have generated and integrated SSL certificate for your website and the Rewrite module is enabled on your hosting server. so that your website can work on HTTPS without any trouble.

There are 2 ways to pass parameters to a dispatching job in Laravel. First is simply call dispatch() or dispatchNow() as per requirement on your Job class like calling a static method on a class: YourJob::dispatch(argument1, argument2, argument3); Second is simply pass arguments while creating an instance/object of Job class then pass the object to dispatch method(always available in the controller) like: $this->dispatchNow(new YourJob(argument1, argument2, argument3)); The arguments will be available in the constructor, can you assign them to class local variable properties and use anywhere in Job class. Let consider below example job: <?php namespace App\Jobs; use Illuminate\Bus\Queueable; use Illuminate\Queue\SerializesModels; use Illuminate\Queue\InteractsWithQueue; use Illuminate\Contracts\Queue\ShouldQueue; use Illuminate\Foundation\Bus\Dispatchable; class Testjob imple...

Assuming you know the basics of Database and know the definition of indexes used in DB, here are some important things about Database indexes about which every good developer must aware of: DB Indexing is used to read data faster, but it makes writing slower. Indexes use in-memory data structures. Indexes use B-Tree (Balanced Tree) data structure to store data and use Binary search for reading/searching. It always saves corresponding DB internal row-id (not table PK) with every indexed node in the B-tree It is not good to add an index to each column of a table. If you have applied index on certain column but in query use any function on an indexed column, the index will not help at all. You can create a combined index on multiple columns. Order matters as per query need. To understand the use of indexes or to know if the query is actually taking the benefit of your index on your column use Explain. Explain give you the execution plan of the query. Explain give you info abou...

When you are working on Ubuntu/Linux OS, some important command given below can help you in managing Users groups and directories. 1. Check user-groups, a user account belongs to: $ groups 2.

Virtual Host is a well-known term in web development. Generally, the remote server where we keep your website code/files is called a hosting server. Similarly, when are working on local system with any installed server like Apache or Nginx, it acts as a host. So to access the website on our system with any a custom domain name like 'yourproject.com' instead of something like 'localhost/yourproject', which sometimes create a problem when accessing relative URLs to base URL of the project. So the best way to create virtual host your local system which we work as the remote website works with a domain name. To Create Virtual Hosts(vhost) for apache2 server in Linux/Ubuntu using terminal follow below steps: 1. Copy default site conf file with the name of the your-website name i.e. laravel-demo.com.conf $ sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/ laravel-demo .conf 2. Open new conf file into an editor with root permission: ...

What are virtual columns?  While developing any web application sometimes we need virtual columns - columns don't actually exist in our DB table, but we drive them from other columns. Why we need them? For example, generally, we use first_name and last_name  in the  users table. But sometimes we also need user's complete name i.e. full_name . There is no benefit of saving full_name in user table if we have already first_name and last_name in the table OR even if we have full_name  as a column in our table then there is no benefit of saving first_name and last_name in the table. So in a scenario like this, we prefer to use the virtual column. Using Virtual Columns in Laravel Considering the first case, in Laravel to get virtual column i.e.  full_name  from the users table will have Accessors. Accessors are methods defined automatically called by Eloquent when select is called on that particular column. Let take an example here: To get full_...
