Rasmus Lerdorf invented PHP in 1994 for personal use and released the first version in 1995 under the name Personal Homepage. PHP is an open-source, server-side scripting language that is embedded in HTML code to create dynamic web pages. PHP scripts are commonly used for server-side scripting, command line scripting, and writing desktop applications. PHP code is written using tags like <?php ?> and uses semicolons (;) to terminate statements.

What is PHP?
Who invented? : Rasmus Lerdorf in 1994
History in 1994,Mr. Lerdrof developed PHP for personal use and then
in 1995,he was released first version of PHP with name PERSONAL
HOMEPAGE,and it was being used on approx 50000 site in 1997.
•PHP stands for PHP: Hypertext Preprocessor.
•PHP is a server-side scripting language
•Open Source Technology
•Robust
•Freeware

How it works

PHP is a general-purpose scripting language that is used in
creating Web pages, and can be embedded in HTML code. (PHP
stands for "Hypertext Pre processor" even though the acronym
doesn't match up exactly.)

PHP is an open-source program, which means it's available for
free on the Web

There are three main areas where PHP scripts are used.
− Server-side scripting.
− Command line scripting.
− Writing desktop applications

PHP Syntax
Method 1: Short Open Tag
<? … ?> // Not Recommended
Method 2:
<?php
….
?>
Each PHP sentence is terminated with semi-colon (;)
EXAMPLE:
<?php echo 'Hello World'; ?>

Comments
Single line Comment
//This is a comment
Multi line comment
/*
This is
a comment
block
*/
EXAMPLE:
<?php
//This is comment
echo '<p>Hello World</p>';
?>

Example
<html>
<head>
<title>PHP Example</title>
</head>
<body>
<?php echo '<p>Hello World</p>'; ?>
</body>
</html>

Literals
All strings must be enclosed in single quote or double quote
Example:
<?php echo '<p>Hello World</p>'; ?>
<?php echo "<p>Hello World</p>"; ?>
NumbersNumbers are not enclosed in quotes
Example:
<?php echo 123; ?>
Booleans can be directly written as true or false

Language Construct
PHP have two language constructs which is used to display data
1. echo()
2. Print()
Language construct can be used with or without brackets
Example:
<?php
echo '<p>Hello World</p>';
print '<p>Hello World</p>';
echo ('<p>Hello World</p>');
print ('<p>Hello World</p>');
?>

PHP is a server-side scripting language that is free to download and use. It was first created in 1994 and is designed to be embedded within HTML code to provide dynamic web page content and functionality. PHP scripts can be placed anywhere within an HTML document and always start with <?php and end with ?>. Comments in PHP can be single line using // or # or multi-line enclosed between /* and */.

Php: An IntroductionLucky Bwaromale Paul

PHP is a server-side scripting language commonly used for web development that allows dynamic content generation on web pages. It was originally created to monitor page views on resumes but has evolved into a fully-featured programming language. Key features include support for HTML, sessions, functions, object-oriented programming, and compatibility with different databases. Major websites that use PHP include Facebook, Yahoo, Joomla, and WordPress. PHP code is written between <?php ?> tags and variables start with a '$' sign.

This document provides an introduction and overview of PHP, a popular scripting language for web development. PHP is open source, supports many databases, is platform independent, and compatible with servers. It also includes built-in security features and tools to protect web applications. The document explains how to set up either XAMPP or WampServer, start the Apache server, and write a simple PHP script to output text to a web browser.

Beginning python programmingkanteshraj

This document provides an introduction to the Python programming language. It begins by asking why Python is needed after showing a simple "Hello World" program in C versus Python. Python is then described as a dynamic, open source language designed for simplicity and productivity. Key features of Python like its interpreter-based nature, clear syntax, portability, large standard library, and suitability for many types of applications are outlined. The document demonstrates basic Python concepts like indentation, lack of variable typing, input/output, comments, and popular Python environments. It concludes by providing references to learn more about Python and announcing an upcoming PyCon conference.

C programming iiKaustavRoy40

To get started with C programming, one prints "Hello World!" by including standard input/output headers, defining a main function that returns 0, and using printf to output the text. Compilers are programs that translate human-readable code into machine-readable binary for a computer to execute. They convert syntax like #include, main(), and printf statements according to language rules. Popular C compilers include Turbo C++, Dev C++, and Codeblocks. Compilers scan entire programs at once and generate object code, while interpreters translate statements individually without object code.

An open source flash workflow using HaXe (2009)dirkcuys

HaXe is an open source programming language that allows developers to write code once and compile it to multiple platforms including Flash, JavaScript, PHP, C++, and NekoVM. It uses a standardized language similar to ActionScript 3 and includes platform-specific libraries to access the full APIs of each target. HaXe code can be compiled to SWF for use on Flash, JavaScript for the web, and other languages for server-side or native applications. Additional libraries can be installed and managed through HaXeLib to provide functionality like physics engines and GUI frameworks.

What the HACK is HHVM?Hean Hong Leong

HHVM is a PHP execution engine created by Facebook that converts PHP code to bytecode, which is then JIT compiled to machine code for improved performance over traditional PHP interpreters. It originated from Facebook's HPHPc compiler and has nearly full PHP compatibility while also supporting a new typed programming language called Hack. A benchmark test demo showed HHVM can provide better performance than traditional PHP interpreters.

What is HHVM? HHVM is an open-source virtual machine designed for executing programs written in Hack and PHP. HHVM uses a just-in-time (JIT) compilation approach to achieve superior performance while maintaining the development flexibility that PHP provides. HHVM supports Hack, PHP 5 and the major features of PHP 7. We are aware of minor incompatibilities, so please open issues when you find them. HHVM also supports many extensions as well.

QBASICnivi88

QBasic is a simple programming language developed by Microsoft as the successor to BASIC for beginners to learn programming fundamentals. It was designed for the MS-DOS operating system and provides an intuitive integrated development environment for writing, compiling, and running programs. While less powerful than other languages, QBasic remains a valuable educational tool for newcomers to learn programming basics due to its extensive documentation and tutorials available online.

Node js Modules and Event EmittersTheCreativedev Blog

The document discusses key concepts in Node.js including modules, using Node.js as a web server with HTTP, managing NPM packages, the event loop, event emitters, and streams/pipes. Modules allow code reuse and sharing functionality. Node.js can be used as a web server by creating an HTTP server to handle requests and responses. NPM is used to install, update, search for, and uninstall third-party packages. The event loop handles asynchronous events and callbacks in Node.js. Event emitters emit and handle events. Streams allow reading/writing files and piping data between streams.
