What is PHP?
Hypertext Preprocessor, also known as PHP, is a popular general-purpose, open-source programming language that is particularly well suited for server-side web development. Websites that are dynamic and interactive are made with PHP. The PHP code has a set of rules, is related to the HTML file or is embedded in the HTML code, and provides unique instructions for how to start and terminate processing.
PHP is a platform-independent programming language that runs on practically all major operating systems, including Microsoft Windows, macOS, RISC OS, Linux, and UNIX versions, and Web Servers like Apache and IIS. The PHP code syntax is fairly simple, but it follows a set of conventions and comes with a set of standard libraries to make web development much easier and more efficient. PHP allows developers to create dynamic web pages and connect them to powerful databases.

PHP is an open-source programming language developed and maintained by a huge community with a strong support base. Because it is free, all you need to get started is a PHP parser, a web server such as Apache, and a web browser such as Google Chrome.
With Ajax, users may change specific information on a webpage without having to reload the page repeatedly. Social networking platforms, for instance, can update likes and dislikes without restarting the page after each activity.
Availability specifies the user who has the authority to edit it. PHP is a renowned open-source language, meaning its source code is freely available to the public. In addition, PHP is owned by the internet community and is open to revisions from its initial design. This is advantageous for PHP developers because there is a plethora of support provided by ordinary users.
Concurrency describes a process in which a task won’t be finished until every thread has finished processing. Thus, all threads start and end simultaneously. PHP’s multi-threaded blocking input/output feature allows for systematically executing many tasks simultaneously.
PHP code can be combined only with HTML Code.
<?php //Single line PHP comment
# Single line PHP comment
/* Multi-line PHP comment */
echo "<p>This is PHP</p>";
//Single line JS comment
Multi-line JS comment */
alert(“This is JS");
$ jsvariabledb = 'value'; // Local variable
global $ jsvariabled; // Global variable
$ jsvariabled = 'value';
var jsvariabled = 'value'; // Local variable
jsvariabled = 'value'; // Global variable
Since JS and PHP are interpreted languages, you can edit your code and then run it again to see the results without recompiling it.
Choose PHP as your backend language when your development project involves:
- Solution stacks like Apache, MySQL, PHP, etc.
- CMS like, WordPress, Joomla, etc
- Servers like PostgreSQL, MariaDB, etc.
- Front-end development frameworks like Angular, React, etc.
- Dynamic Single Page Applications
- Technologies for servers, including MongoDB, Express.js, Node.js, etc.
- Solutions Stacks like MEAN, Express js, MongoDB, etc.
