Security is Everyone's Job


PHP is a server-side scripting language that can make web pages dynamic and interactive

It was created in 1995 by Rasmus Lerdorf, who was working at Netscape at the time.

He wanted to create a language that was easy to use and could run in the browser without needing a compiler.

PHP is based on the ECMAScript standard, which defines the syntax and features of the language.

There are many versions of ECMAScript, and the latest one is ECMAScript 2021

PHP can also use additional features and libraries that are not part of the standard, such as the Document Object Model (DOM), which allows PHP to manipulate HTML elements on the page

What PHP is for

PHP is used for many purposes, such as creating web applications, games, animations, data visualization, server-side programming, and more.

It can run on any device that has a PHP engine, which is a program that interprets and executes PHP code.

Some examples of PHP engines are Zend Engine (used by PHP 5 and 7), HHVM (used by Facebook), and Quercus (a Java implementation of PHP)
