Make your first CRUD with PHP - Part 3: Create

In most cases applications are meant to treat/process data. No matter the data the application processes or no matter how it does it, there are some common points any application considers: the data `input` phase, `processing` phase, and an `output` phase. The `input` phase consists of the application require some little information in order to give an appropriate feed back. In the case of a website, we usually use forms to ask user to enter their details in order for our application to recognize them as member or other things. Once the application has this information, it has to store this data somewhere, either in a database, a file, in session, or in cookies, etc. That action of saving the data is called the *creation phase*, or simply `CREATE`. In our case here we will be saving our data into a database.
