Create Notes App using PHP (OOP) , Bootstrap and jQuery

0 8,563

A notes app using object-oriented programming (OOP) in PHP would be a web-based application that allows users to create, read, update, and delete notes through a web browser. The application would be built using the OOP features of the PHP programming language, such as classes, objects, and inheritance. The app would use classes to represent the different components of the application, such as the user, the notes, and the database. These classes would contain methods that perform the operations related to the notes, such as creating, reading, updating, and deleting notes.

The data validation, processing, and storage would be handled by methods in the classes which would encapsulate the data and methods together, this would make the code more organized, maintainable, and easy to understand. The app would use a database to store the notes, and a PHP Data Object (PDO) would be used to interact with the database. The user interface would be generated using HTML, Bootstrap, and jQuery, and the PHP code would handle the server-side logic, such as processing form submissions and rendering the pages.

It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.

Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for \\\\\\\\\\\\\\\'lorem ipsum\\\\\\\\\\\\\\\' will uncover many web sites still in their infancy.

This book is a treatise on the theory of ethics, very popular during the Renaissance.

2- Creating Database Connection

A PHP MySQL database connection refers to the process of connecting to a MySQL database from a PHP script. This is typically done using the MySQLi or PDO extension in PHP. The MySQLi extension provides an object-oriented interface, while PDO (PHP Data Objects) provides a data-access abstraction layer.

Goto master.php file and see the database connection  code

$this->conn = new mysqli("localhost", "root", "mysql", "note");

Download Source Code

Running PHP code in a localhost environment allows you to test and debug your PHP scripts on your own computer before deploying them to a live web server. To run PHP code on a localhost, you will need to install a web server software, such as Apache or Nginx, and a PHP interpreter on your computer.

One of the most popular way to set up a localhost environment is to use XAMPP. XAMPP is a free, open-source package that includes Apache, MySQL, PHP and Perl. Once you have XAMPP installed, you can start the Apache and MySQL modules using the XAMPP Control Panel, and then you can put your PHP files in the “htdocs” folder located inside the XAMPP installation directory. Once you have done that, you can access your PHP files in a web browser by typing “http://localhost/note” in the URL bar.

Alternatively, you can use other software that includes a built-in web server, such as MAMP for Mac or WAMP for Windows, which can be used in a similar way as XAMPP.

It’s important to note that when running PHP code on a localhost, you will not have access to the same server-side resources as you would on a live web server, such as a mail server or a database server. You will need to configure those separately on your localhost environment.
