at Key  Features and 
Best  Practices
Introduction to 
PHP
PHP is a popular server-side scripting language used to create dynamic web pages and web applications. It was initially 
created by Rasmus Lerdorf  in 1994 as a collection of Common Gateway Interface (CGI) scripts and has since evolved into a 
powerful and flexible language.
PHP was originally created by Rasmus Lerdorf in 1994 as a set of CGI scripts to help track visitors to his personal website. 
Over time, it evolved into  a more robust language, with the first version of PHP, PHP/FI, being released in 1995. In 1997, two 
developers named Andi Gutmans and Zeev  Suraski rewrote the language's core and released PHP 3.0, which was the first 
version to resemble the PHP we know today. The most recent major  version of PHP, PHP 8.0, was released in November 
2020.
PHP offers several advantages, 
including:  Open-source

PHP 
Features
Ease of use: PHP has a simple and intuitive syntax that is easy to learn, making it a popular choice for beginners and 
experienced developers  alike.
Flexibility: PHP is a flexible language that can be used to build a wide range of web applications, from simple websites to 
complex enterprise-  level applications.
Server-side Scripting: PHP is a server-side scripting language, which means that it runs on the server side and generates 
HTML output that is  sent to the client's browser. This makes it possible to create dynamic web pages that can be 
customized based on user input and other factors.  Database Support: PHP has built-in support for several databases, 
including MySQL, PostgreSQL, Oracle, and Microsoft SQL Server. This makes  it easy to create database-driven web 
applications that can store and retrieve data.
Cross-platform Compatibility: PHP is compatible with a wide range of operating systems, including Windows, Linux, 
macOS, and Unix. This  makes it easy to develop and deploy PHP applications on different platforms.
Large Community: PHP has a large and active community of developers who create libraries, frameworks, and tools that 
make it easier to  develop PHP applications. This also means that there is a lot of documentation and support available 
for PHP developers.
Security Features: PHP has several security features, such as input validation and encryption, that help to protect web 
applications from  attacks like SQL injection and cross-site scripting.
