PHP MySQL Database

PHP with MySQL is one of the most powerful and widely used combinations for developing dynamic and database-driven websites.

PHP is a popular server-side scripting language used to create interactive web applications, while MySQL is a reliable relational database management system used to store and manage data securely. Together, PHP and MySQL allow us to easily insert, retrieve, update, and delete data in real time.

This combination allows us to build modern web applications such as login systems, registration forms, content management systems, and e-commerce websites. Today, many popular platforms, including WordPress and Facebook (in its early development), are using PHP with MySQL to manage millions of users and their large amounts of data efficiently.

Since both PHP and MySQL are open-source, easy to learn, fast, and supported by almost all web hosting providers, they are an excellent choice for beginners who want to learn web development.

In this PHP MySQL tutorial, you will learn what MySQL is, and how to install it on your system step by step.

What is MySQL?

MySQL is an open-source relational database management system (RDBMS) used to store, organize, and manage data efficiently. It stores and manages data in tables using rows and columns. It is supported and maintained by Oracle Corporation, which provides both free and a commercially licensed versions of the software with additional features.

MySQL uses Structured Query Language (SQL) to perform various database operations, such as inserting, retrieving, updating, and deleting data from the tables.

MySQL runs on a database server that manages data securely and efficiently. It allows users and applications to access and manipulate data easily. Therefore, it is widely used along with PHP to build dynamic and data-driven websites and applications.

Features of MySQL Database System

Some important features of MySQL database system are:

• MySQL is one of the most popular relational database management systems in the world.
• It runs on a server that stores, manages, and controls access to the structured data.
• It is suitable for both small and large-scale applications.
• MySQL is fast, reliable, and easy to use.
• It uses standard SQL to interact with and manage the database.
• MySQL supports multiple operating systems, such as Windows, Linux, and macOS.
• MySQL is open-source, so you can download and use it for free.
• It provides strong security features, such as user authentication and access control, to protect data.
• The data in a MySQL database is stored in tables consisting of rows and columns.
• MySQL allows multiple users to work with the database simultaneously.

Why Use PHP with MySQL?

We commonly use PHP combined with MySQL together to build dynamic and database-driven websites.

PHP is used to:

• Connect to the database.
• Insert data into the database.
• Retrieve data from the database.
• Update existing data.
• Delete data from the database.
• Process and display data on web pages.

MySQL is used to:

• Store data permanently.
• Organize data into tables.
• Manage and handle large amounts of information.
• Provide fast and secure data access.

Let us understand all these points with a real-time example.

Realtime Example

When you fill out a login form, PHP checks your username and password stored data in the database. MySQL stores all user accounts, passwords, and website content in its tables. So, you can understand it like this:

• PHP = Worker (handles tasks and communicates with database)
• MySQL = Storage Room (stores and organizes data)
