Introduction to PHP and MySQL

Introduction to PHP

  • Only executed on a server - can’t just be opened in browser like HTML files
  • Interacts with database but only through queries
  • Like Python, data types (int, string, bool) are optional for function parameters and return values, though omitted from variables in PHP

In the next post, you will learn the syntax of PHP so you can start writing it. It may look familiar if you already know other high level programming languages.

Introduction to MySQL

  • It is a type of Database management software (DBMS) - it manages a database
  • A database can contain multiple tables, each containing records
  • Tables are created with a data structure detailing what fields will be stored
