This document provides an overview of PHP, including its history, usage, syntax, frameworks, and more. PHP was created in 1994 by Rasmus Lerdorf as a general purpose scripting language especially suited for server-side web development. It allows developers to embed PHP code into HTML files to produce dynamic web pages. Major updates included support for object oriented programming, XML, and improved performance. PHP is a popular open source language used by over 240 million websites.

- 5. HISTORY PHP (PHP: Hypertext Preprocessor) was created by Rasmus Lerdorf in 1994. It was initially developed for HTTP usage logging and server-side form generation in Unix. PHP 2 (1995) transformed the language into a Server-side embedded scripting language. Added database support, file uploads, variables, arrays, recursive functions, conditionals, iteration, regular expressions, etc. PHP 3 (1998) added support for ODBC data sources, multiple platform support, email protocols (SNMP,IMAP), and new parser written by Zeev Suraski and Andi Gutmans . PHP 4 (2000) became an independent component of the web server for added efficiency. The parser was renamed the Zend Engine. Many security features were added. PHP 5 (2004) adds Zend Engine II with object oriented programming, robust XML support using the libxml2 library, SOAP extension for interoperability with Web Services, SQLite has been bundled with PHP PHP 6 and Unicode(2005) lacking native Unicode support at the core language level PHP 7(2015) (PHP next generation), which aims at optimizing PHP performance by refactoring the Zend Engine while retaining near-complete language compatibility.
- 6. WHAT IS PHP? • PHP is a scripting language that was originally designed for web development to produce dynamic webpages. • For this purpose, PHP code is embedded into HTML • PHP originally stood for ”PERSONAL HOME PAGE” - now - Hypertext Preprocessor • Installed on more than 240 million websites • Cost-effective, Scope for Customization, Faster, Preferred over others
- 7. USAGE • PHP is a general-purpose scripting language that is especially suited to server-side web development where PHP generally runs on a web server. • PHP code in a requested file is executed by the PHP runtime, usually to create dynamic web page content. • PHP is also used for command-line scripting and client-side GUI applications. • PHP can be deployed on most web servers, many operating systems and platforms, and can be used with many relational database management systems.
- 8. RESOURCES • PHP includes free and open source libraries. • PHP is a fundamentally Internet-aware system. • Many database servers, embedded SQL libraries such as embedded PostgreSQL, MySQL and SQLite, LDAP servers, and others. • PHP allows developers to write extensions in C to add functionality to the PHP language. • These can then be compiled into PHP or loaded dynamically at runtime.
