The MySQL database uses Structured Query Language (SQL), a programming language for interacting with relational databases. SQL consists of four types of statements: Data Definition Language (DDL): Create/modify database structure Data Manipulation Language (DML): Insert/Update/Delete/Retrieve data Data Control Language (DCL): Grant/Revoke Access Transaction Control Language (TCL): Managing Transactions
What language does the MySQL database use?
MySQL database uses Structured Query Language (SQL), which is a programming language specifically designed to interact with relational databases.
SQL Introduction
SQL is a non-procedural language, which means that it does not specify how the database executes commands, but only the commands to be executed. It consists of a series of commands and keywords used to create, modify and retrieve data in the database.
SQL statement types
SQL consists of four main types of statements:
- Data Definition Language (DDL): Used to create and modify database structures, such as tables, indexes, and views.
- Data Manipulation Language (DML): Used to insert, update, and delete data, and perform other data-related operations.
- Data Control Language (DCL): Used to grant and revoke access to database objects and data.
- Transaction Control Language (TCL): Used to manage transactions, a series of database operations that are performed as a single unit.
Using SQL in MySQL
In MySQL, you can use SQL statements to perform various tasks, including:
- Create and modify databases and tables
- Insert, update and delete data
- Execute queries to retrieve data
- Grant and revoke user permissions
- Manage transactions
Advantages of SQL
SQL as a database language has the following advantages:
- Standardization: SQL is an international standard, which means it can be used in different database systems.
- Non-procedural: It does not specify how the database executes the command, but focuses on achieving the results of the command.
- Powerful functions: SQL provides a series of commands and keywords that allow you to perform various database operations.
- Easy to learn: SQL is a relatively easy language to learn, with simple syntax and easy-to-understand commands.

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
