PHP Hypertext Preprocessor is a server-side scripting language. Most websites are one of the basic web technologies that use this language. Developers can build websites that are running dynamically. PHP includes some precise and great features that allow developers to create feature-rich web pages and database-based sites. The framework helps build highly interactive web pages such as photo galleries and login pages. Because PHP is open-source, it can run on most operating systems available today, including Windows, Mac OS, Linux, and UNIX. Learning PHP and using it is very simple.
In other words, it is a programming language that contains HTML for various tasks, such as creating custom web content, sending and receiving cookies, and evaluating form data sent from the browser. Databases such as PostgreSQL, Oracle, Sybase, SQL MySQL, etc. PHP also supports major protocols such as IMAP and POP3 LDAP.
PHP allows you to process forms, store data in files and collect data from files, return data to users, and more.
Example: Imagine a website that allows users to see the status of their orders after logging in. It queries the database via PHP coding and outputs information about a particular user based on the information in the database.
Server Side vs Client-Side Scripting:
PHP is a server-side scripting language. This means it runs on the web server, not on the client machine.
Server-side programming helps to deliver dynamic content (usually a database) to the user, such as a welcome message (“Hello, Alex!”) when the user logs in.
Frontend vs backend:
PHP runs on the backend of your website. This is the part that is not visible to visitors. This means PHP doing all the work on a given web server and its admin.
The Runtime environment:
If you are in the middle of choosing the right back-end technologies, consider the following points:
Pick PHP as your backend language when your project covers:
- Solution stacks like LAMP (Apache, Linux, MySQL, PHP).
- CMS like Drupal, WordPress, Joomla, etc.
- Servers like PostgreSQL, MariaDB, Oracle, Sybase, etc.
- Front-end technologies like Angular js, React js, Backbone.js, Ember.js, etc.
- SPAs (Dynamic Single Page Applications)
- Server Technologies like MongoDB, Express.js, Node.js, etc.
- Solutions Stacks like MEAN (Express js, Angular js, MongoDB, etc.)
