PHP and MySQL

Table of content

PHP (Hypertext Preprocessor) is a programming language that is widely used for creating dynamic web pages. It can be embedded into HTML and is often used in conjunction with a database to store and retrieve data. PHP is a server-side language, which means that it is executed on the server rather than in the user's web browser. This allows PHP to perform tasks such as reading and writing to files, generating dynamic web content, and interacting with databases. One of the advantages of using PHP is that it is easy to learn, especially for those who are already familiar with languages such as C or C++. PHP code is written in plain text and is typically saved with a .php file extension. To use PHP, you will need a web server that supports PHP and a text editor to write your code. When a user requests a PHP page from your website, the server processes the PHP code and sends the resulting HTML to the user's web browser. PHP is a popular choice for web development because it is powerful, flexible, and easy to use. It is used by many large websites and is supported by almost all web hosting providers.

 

PHP editor
There are many text editors that you can use to write PHP code. Some popular options include:
Notepad++: A free, open-source text editor that is popular among PHP developers.
Sublime Text: A paid text editor that is widely used by developers due to its features and customisation options.
Visual Studio Code: A free, open-source text editor developed by Microsoft that is popular among developers due to its powerful features and extensions.
Atom: A free, open-source text editor developed by GitHub that is popular among developers due to its customisable interface and features.
Eclipse: A free, open-source text editor that is popular among developers due to its powerful features and integration with various programming languages.
PhpStorm: PHPStorm is a popular choice among PHP developers due to its powerful features and user-friendly interface. However, it is a paid tool, so you will need to purchase a license to use it.

 

Basic Features:

  • Server-side Scripting: Most commonly used for creating dynamic web pages.
  • Database Integration: Can connect to multiple types of databases, most notably MySQL, SQLite, and PostgreSQL.
  • Sessions and Cookies: Native support for creating and managing sessions and cookies.
  • File Handling: Can read and write files on the server.
  • Object-Oriented Programming: Supports OOP features like classes, inheritance, and interfaces.

Web Development Frameworks

PHP has a number of frameworks that make it easier to develop web applications. Some of the popular PHP frameworks are:

  • Laravel
  • Symfony
  • Zend Framework
  • CodeIgniter
  • Yii 2

Getting Started

To get started with PHP, you typically set up a web server environment like Apache or Nginx and install PHP. Another easy way is to use pre-packaged solutions like XAMPP or WAMP for Windows, or LAMP for Linux, that include Apache, MySQL, and PHP bundled together.
