PHP is a general-purpose, open source, server-side scripting language used for building dynamic websites and apps. PHP is utilised to build almost 79% of the websites in their database, according to a W3Tech survey. It is used to build not just online apps for several tech giants such as Facebook, but also various CMS (Content Management System) like as WordPress, Drupal, Shopify, WooCommerce, and so on . What Are The Benefits Of Using PHP? PHP can handle all aspects of server-side programming known as a website's backend. PHP, for example, may accept data from forms, generate dynamic website content, interface with databases, create sessions, send, and receive cookies, and send emails. It's possible to use a server-side script language with the help of several hash algorithms. Later tutorials will teach you more about these skills.

Even if the aforementioned PHP skills do not convince you, there are some further PHP functionalities. PHP is compatible with most major operating systems, including Windows, Linux, Unix, and MacOS X. Almost all of today's major servers, including Apache, support PHP. PHP is compatible with a wide range of databases. The most essential aspect is that it is absolutely free to use and download, and PHP can be got from its official website.

You've probably heard of several programming languages; you might ask why we'd choose to utilise PHP as our poison for web programming. Here are several convincing explanations.

● PHP is a free source programming language.

● The learning curve is relatively quick in contrast to other languages such as JSP, ASP, and others.

● A vital community documents

● Unlike other languages that require IIS, most web hosting servers accept PHP by default. As a result, PHP is an inexpensive option.

● PHP is regularly updated to stay up with the most recent technological advances.

● Another advantage of PHP is that it is a server-side scripting language, which means you just need to install it on the server, and client computers that access server resources do not require PHP; a web browser suffices.

● Although PHP includes built-in support for communicating with MySQL, this does not exclude you from utilising PHP with other database management systems.

PHP is still usable with

● Postgres ● Oracle ● MS SQL Server ● ODBC etc.

PHP is cross-platform, which means it can run on a variety of operating systems such as Windows, Linux, and MacOS.

How Does PHP Function in WordPress? Most of the files in the ZIP file you download from WordPress are in PHP format. Because WordPress is built on PHP, this is the case. There are various PHP files in the root folder that can be altered and changed.

Before we begin, keep in mind that different PHP versions are available. WordPress 5.6 and later are compatible with the most recent version of PHP, 8.0. Experts recommend that you always use the most recent version to maximise the performance of your webpages.

PHP Is A Programming Language For Computers. The PHP (Hypertext Preprocessor) programming language is widely used for "server-side" web development. To understand everything, you must first grasp the concept of a scripting language. Scripting languages (a subset of coding languages that includes PHP and languages such as JavaScript and Ruby) are used to automate procedures that would otherwise have to be done step by step in a site's code every time they occur.

This includes things like dialogue boxes that appear on a screen in response to a user's actions, chatbots that respond to defined user behaviour with corresponding messages, or animation that appears when a user scrolls past a certain point on a page—any dynamic website functions that need to occur on screen without the user manually reloading a site. Scripting languages, such as PHP, differ from markup languages in that, whereas HTML and CSS decide the style and appearance of web pages, scripting languages instruct a static web page (made with HTML and CSS) to "perform" specified activities. This may sound familiar if you've spent any time reading about JavaScript.

PHP Is A Server-Side Scripting Language As previously stated, PHP is primarily used as a server-side language (as opposed to languages such as JavaScript, which is normally run on the client-side). So, what does this all mean? Client-side refers to website activity that occurs locally on a user's computer through the use of a web browser. Client-side languages such as HTML, CSS, and JavaScript provide instructions for web browsers to parse and translate into text shown on your computer screen. It is noteworthy that JavaScript isn't on the list (a programming language similar to PHP). Again, JavaScript-scripted processes take place on the client side—JS gives instructions that your web browser can understand and execute. When you use the internet, you see the client-side.

Server-side activity involves a web browser sending requests to a web server (the software or hardware that holds a website's pages, images, media, and other assets), which then answers with HTML code that the web browser can process, render, and display on the user's screen. The key distinction between this process and client-side activity is that it includes communication with a server and is not completed wholly within the client's browser.

A client-side scripting language, such as JavaScript, can automate tasks involving content already present in a user's web browser, whereas a server-side scripting language, such as PHP, is used to request content from a website's server or database and make that content visible and accessible to the site's user. To ensure website efficiency, loading speeds, and storage space, not all assets can be hosted locally on web pages at all times.

PHP Applications Here are a few PHP apps to strengthen your faith in this fantastic scripting language:

● It can build Web applications such as Social Networks (Facebook, Digg), Blogs (WordPress, Joomla), eCommerce websites (OpenCart, Magento, and so on).

● Scripting on the command line. PHP scripts can be written to do various tasks on any system; all you need is a PHP parser for this.

● Using Facebook's PHP SDK, you can simply create Facebook applications and incorporate Facebook plugins into your website.

● Because PHP includes a sophisticated email sending function, you can send emails or construct email applications.

● Wordpress is a popular blogging (CMS) platform around the world, and if you know PHP, you can try your hand at Wordpress plugin creation.

Popularity Is Dwindling PHP is still a relatively new language among software developers. However, with so many options currently available, it is a dying language. As a programming language, PHP ranks sixth in PYPL (Popularity of Programming Language). The TIOBE index rates PHP as the tenth most popular programming language accessible today, while Stack Overflow research ranks it eleventh.

Who Employs PHP? Despite the fact that PHP has been around for a long time, it is still utilised by some of the world's most well-known organisations and websites. Below is a list of some companies that use it.

● Facebook ● Wikipedia ● WordPress ● Etsy ● Slack

Learning PHP remains a valuable investment for developers even though it may no longer rank number one.
