What is PHP and Why Should You Learn It?
In an age of intimidating, large-scaled tech stacks, PHP remains widely used in the web development niche. The use of PHP is nearly everywhere on the web. It is estimated that 79.1% of all websites with a recognized server-side programming language use PHP.
PHP is an acronym for “Hypertext Processor” and was first released by Danish-Canadian programmer Rasmus Lerdorf in 1995. PHP scripts can be easily embedded into HTML documents that are served at the front end of the server. An interpreter acts as a backend module integrating into the webserver. Thus, PHP is an excellent choice for building full-fledged websites based on static HTML.
A neat feature of PHP is that it's very flexible and versatile. PHP is almost the same as if it was an object-oriented language, making it a very convenient language to work with. It also has a quite powerful meta-language for developers.
PHP is typically used to run Web sites, but you can run PHP on your Windows, macOS, and Linux workstations. The easiest way to run PHP is to install Docker and then run a container with PHP included. The container referred to in the link has PHP, MySQL, and NGINX running in a single container. You can be up and running in a few hours.

Top 8 Practical Applications of PHP
Some common web applications that can be created with PHP include:
A web page or web application is required to offer high levels of customization, a very interactive user interface and should be able to perform online transactions and integrate with database systems. PHP ensures all these features are achieved through its three-tiered architecture that works in a linear fashion on browser, server, and database systems. This explains why more than 82% of websites use PHP for server-side programming. Numerous web-based applications and Facebook apps are scripted in PHP too.
PHP can be used to build both static and dynamic web pages and web-based applications. Developers can manipulate the coding to reuse it in other applications too. Built-in mechanisms like support for user authentication, SQL query builder, CSRF protection, and routing make PHP one of the most in-demand programming languages. Besides being an open-source platform with free licensing, PHP enjoys high popularity among programming languages.
PHP supports various databases like Oracle, MySQL, and MS Access and is designed to interact with other services using protocols such as HTTP, LDAP, POP3, IMAP, NNTP, SNM, and COM. Many PHP frameworks offer templates, libraries through which developers can manage and manipulate the content of a website. Thus, PHP is used to create small static websites as well as large content-based sites. Some of the best Web Content Management Systems (CMS) managed by PHP are WordPress and its plugins, user interface of Drupal, Joomla, Facebook, MediaWiki, Silverstripe, and Digg, among others.
No matter how small or big a business is, online selling is an indispensable part of any venture today. The use of PHP frameworks like CakePHP and CodeIgniter helps create ecommerce applications quickly and efficiently. Popular ecommerce platforms like Magento, OpenCart, Zen Cart, PrestaShop, AgoraCart, and Ubercart are all practical applications of PHP.
Another important use of PHP can be for creating desktop Graphical User Interface (GUI) based applications. Prominent tools that allow scripting in PHP are PHP-GTK 2 and ZZEE PHP GUI, which compile PHP into.exe that can run on its own.
Many PHP frameworks provide an open-source library like Ming to create Flash in .SWF file format, which contains features like gradients, bitmaps (.png and .jpeg files), morphs, text, shapes, buttons, actions, and animations. Plus, it’s simple to create and incorporate flash elements like login-form and email form into dynamic web pages with the use of PHP.
Also prominent among applications of PHP is its use to manipulate images. Various image processing libraries like Imagine, GD library, and ImageMagick can be integrated with PHP applications to allow a wide range of image processing features, including rotating, cropping, resizing, adding watermarks, creating thumbnail pictures, and generating output images in many formats. The different formats of output images can be jpeg, gif, wbmp, xpm, and png. This is an essential prerequisite for creating robust websites and web applications.
PHP can be used to create various means of data representation like charts, graphs, and scatter-dot plots by using tools such as Image_Graph. This feature is commonly used across client-side ecommerce websites, desktop applications, and various other applications where data must be presented succinctly and graphically.
Creating PDF files is another important application of PHP. A built-in library tool called PDFLib can be used to generate and manipulate PDF files using PHP. This helps in creating an online invoicing system where we can create an HTML-driven invoice in PDF (Portable Document Format) file.
The fact that PHP can be embedded with HTML makes it highly accessible for new programmers. Unlike languages like C or Java, PHP does not require complex processes to generate HTML page. Thus, PHP offers a host of possibilities, from creating simple websites to highly complex systems like virtual stores and online management platforms.
