What is PHP?

PHP is an acronym for Pre Hypertext Preprocessor. PHP is code run server-side that outputs HTML, but can also be used to output other formats such as CSS, JavaScript and many more.

A PHP file can also contain several different data types, such as data structures, arrays, strings, or number fields

PHP is a server-side scripting language

PHP is a popular server and scripting language used for web development and the development of web applications. PHP is often used to write dynamically generated web pages and is one of the most popular and widely used web scripting languages in the world.

The worlds most popular content management system, WordPress, is developed in PHP.

Besides building interactive Web pages, PHP can also be embedded in web applications such as mobile apps.

PHP is used to create web pages, store and send e-mails and respond to e-mails and files you upload or download. The output of a PHP script is HTML, which is then rendered by the web browser.

PHP scripts are server-side scripts, meaning the code is executed on the server, and the results are sent to the web browser in pure HTML. The HTML is then rendered in the browser and the user is shown the website.

PHP can be directly added to HTML

HTML can also be used to develop static websites, while PHP can be used to create components that make your website dynamic.

PHP can be used to embed forms into a web page. When the form is submitted, PHP code is executed that will send you an e-mail to notify you of the form's submission and the contents.

While many programming languages can be used to create web applications, PHP is one of the few languages designed specifically for the web. Consider the ability to easily connect to MySQL, Oracle, and other databases, as well as the ease of installation on a web server.

One of PHP's nice features is its you can insert parts of your code into the HTML of a page. You can insert PHP into HTML code, save it as .php and run it using Nginx or Apache.

When the web page is visited, PHP processes the code and sends the web browser the HTML output, which is then rendered by your web browser.

Therefore, scripting in PHP can be as simple as programming HTML manually or as complex as is needed in your website development.
