Introduction to SQL Databases in PHP for Beginners

A database (abbreviated as DB) is a place where website data is stored. This can include page texts, lists of users with their logins and passwords, product catalogs, and more.

A database consists of tables. You know what a table is from real life: it has rows and columns. And at the intersection of rows and columns are cells.

In databases, columns are often called fields, and rows are called records.

The database itself is a program that stores data and allows this data to be retrieved and modified.

Retrieving and modifying data is done using queries. Queries are commands written in a special language - SQL.

Working with databases through PHP is not particularly difficult. The only potential challenge is the long initial preparatory stage, which will stretch over several lessons.

But, after we prepare everything, things will become much easier.
