HTML and PHP INTRODUCTION

HTML and PHP INTRODUCTION

PHP is a scripting language originally designed for producing dynamic web pages. It has evolved to include a command line interface capability and can be used in standalone graphical applications.

PHP is a widely-used general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

While PHP was originally created by Rasmus Lerdorf in 1995, the main implementation of PHP is now produced by The PHP Group and serves as the de facto standard for PHP as there is no formal specification.

PHP is free software released under the PHP License, however it is incompatible with the GNU General Public License (GPL), due to restrictions on the usage of the term PHP.

It generally runs on a web server, which is configured to take PHP code as input and create web page content as output. It can be deployed on most web servers and on almost every operating system and platform free of charge. PHP is installed on more than 20 million websites and 1 million web servers.



What is PHP?

PHP is a server-side, cross-platform, HTML embedded scripting language.

Server-side:  

php

This means that PHP scripts execute on the Web server, not within the browser on your local machine.

Cross-platform: 

Cross-platform means that PHP scripts can run on many different operating systems and Web servers. PHP is available for the two most popular Web server configurations (IIS running on Windows NT and Apache running on UNIX).

HTML embedded scripting language:  

This means that PHP statements and commands are actually embedded in your HTML documents. When the Web server sees the PHP statements in the Web page, the server executes the statements and sends the resulting output along with the rest of the HTML.

PHP commands are parsed by the server much like Active Server Pages or Cold Fusion tags.

HTML Document structure and it's Syntax format

  HTML Document structure and it's Syntax format: HTML is the abbreviation for Hypertext Markup Language, which is utilized to make HTML web pages that are displayed on browsers. The set of rules and guidelines that make HTML code work is known as its syntax.    HTML Syntax Structure Overview    Angle brackets (<unk> and >) are used to enclose tags that represent elements in HTML documents.  The fundamental idea is that an HTML element consists of a start tag, content, and a closing end tag.    <start tagname>content</end tagname>      The arrangement of tags is usually in pairs, with the opening tag preceding the content and the closing tag following it.In closing tags, the tag name is preceded by a forward slash (/).    [Google Ads] Example looks like:    <b>This is a paragraph element.</b>        HTML tags, which are not visible in a browser, determine the document's display.
