Here is the very basic of PHP learning part. Everyone who starts to learn basic PHP from scratch should have learned basic HTML and basic CSS beforehand. But if you simply would like to add up your web programming comprehension, the introduction to PHP is a good read for you.
We also provide basic HTML and CSS topics that you can follow. It would be better if you learn a web programming language step by step. So you would understand how to learn a web programming language from scratch and know what it is used for.
You may find out that you get distressed in learning PHP code if you have not mastered yet basic HTML and basic CSS. And eventually, ends up in a lazy-coding.
This article is a quick introduction to PHP that will explain what PHP programming language is. The next lesson you will learn the structure of PHP syntax writing, the nature of PHP, how to run PHP files, and how a web server runs PHP code. But now, let’s start to learn the basic introduction of PHP programming language.
Introduction to PHP
PHP stands for Hypertext Preprocessor (in its recursive acronym) but originally stood for Personal Home Page. PHP is one of the most popular web programming languages that is designed specifically for web developments. PHP has a server-side nature as it’s executed or from the server side. In other words, it’s running from the server side or run on the server computer but not on the client computer. PHP is run through a web browser application just like how HTML run. Almost all types of websites are developed using PHP code such as WordPress, Joomla, Twitter, Facebook, Wikipedia and other well-known sites.
PHP was developed in 1995 by Rasmus Lerdorf. You can visit the official website of PHP, www.php.net. If you learn basic HTML and CSS, you certainly would be able to take a conclusion that HTML is used to make the foundation of a webpage, and CSS is used to design its style. Then, on this PHP introduction, you will know what it is and how its importance in building a website that consists of static pages and so on.
PHP Functional and Usability
If we assume that the foundation of a home building is PHP, HTML then is its piles, roofs, floors, and walls. But up to here, we are not yet talking about its colors, styles, doors, and rooms. If the foundation, walls, and the structure of home building have been built, its look is certainly still very monotonous and unsightly to our eyes. That’s why we use CSS to make the look and styles of the entire house layout become more attractive and comfortable in our eyes.
That simple parable may make you wonder what PHP is used for. PHP is used to make who can go into the house, who can see the house, and who can store, save, or dispose of things from-and-into the home building. So, PHP is essentially useful for making some certain actions on the house or website in the real example.
PHP Syntax Writing
To write PHP syntax you need to start it with a “<?php” opening tag and end with a “?>” closing tag (without quotes and bold). You can insert PHP syntax in a file with a .php extension or parts of an HTML file. Then, you should end each line of the PHP syntax with a semicolon (;). The following is how to write a PHP syntax.
<?php echo "This is how PHP syntax writing look like."; ?>
You can see in the structure of the PHP syntax above that at the very beginning it must be opened with the right PHP opening tag and ends with the right PHP closing tag. But once again, take note that the line of your PHP code will not work properly if you don’t end the line a with semicolon or semicolon.
Next, the function of the echo syntax is to view the data. And that PHP example generates a written text data; “This is how PHP syntax writing looks like.” on the browser which its elements are seen as a single HTML file or webpage on the client computer. It’s why we said previously that PHP has a server-side nature. In which, no client would know whether a webpage is created using a plain HTML file or generated by a PHP file(s) unless the webmaster.
If you learn PHP more deeply, you will then understand why people create dynamic websites using PHP, but not HTML.
How to run PHP on Localhost
After you learn the introduction to PHP and a glance of PHP syntax structure, you should learn also how to run PHP syntax on localhost (local server). You can make your own local server on your computer using XAMPP, WAMPServer, or other similar local server software programs. This way makes you possible to practice PHP coding on your computer.
