Introduction

PHP stands for “PHP: Hypertext Preprocessor”. It is a widely used, open-source server-side scripting language used to build dynamic and interactive websites.

PHP scripts run on the server, not in the browser, which means the data is processed on the server first and then sent to the user’s browser as a web page. It is also free to download and use

PHP is a powerful server-side scripting language used for building dynamic and interactive websites. It is designed to work efficiently on different systems and web environments, making it very flexible for developers.

PHP can run on many operating systems like Windows, Linux, Unix, and macOS. It also works smoothly with popular web servers such as Apache, Nginx, and others. In addition, PHP supports many types of databases like MySQL, PostgreSQL, Oracle, and MongoDB, which makes it very useful for data-driven applications.

A PHP file is a web file that is saved with the .php extension and is used to create dynamic web pages. It can include PHP code along with HTML, CSS, JavaScript, and text.

When a PHP file is opened through a web server, the PHP code is processed on the server side, and only the final result is sent to the browser in the form of HTML output

PHP is a powerful server-side scripting language that is mainly used to build dynamic and interactive websites. It can perform many important tasks on web applications.

• Create dynamic web pages (content changes based on user input)
• Work with databases to store and retrieve data
• Build login and registration systems
• Handle form data (like contact forms, sign-up forms)
• Develop e-commerce websites (shopping carts, orders)
• Manage files on the server (create, read, delete files)
• Connect with other services and applications
• Send emails from web applications

PHP 8 is a major update of PHP that brings new features, better performance, and improved code quality. It makes PHP faster, more modern, and easier to use.

• Just-In-Time (JIT) Compiler – for faster execution times and improved performance
• Union Types – allow variables and function return types to accept multiple types
• Named Arguments – allows to pass arguments to functions or methods by their name
• Match Expressions – a more powerful and concise alternative to the traditional switch statement
• Nullsafe Operator (?->) – an easy way to access the properties and methods of an object when it may be null
• Attributes – allows you to add metadata to your code
• Improved Error Handling
• New Functions – like str_contains(), str_starts_with(), str_ends_with(), and get_debug_type()
