What Is PHP?
The full form of PHP is Hypertext Preprocessor, it is a server side scripting language which is used in web development. Server side scripting i.e. a program written in PHP is always run in the server and whatever is output is converted as an HTML page and displayed on the user's web browser.
The HTML and CSS code of a website can be seen but the PHP code cannot be seen by the user because its code always resides in the server and never reaches the client's system. PHP is a very powerful language and today millions of websites on the internet are using PHP.
Almost all popular CMS like WordPress, Joomla, Drupal etc. are made from PHP. PHP is being used everywhere, be it e-commerce or social networking sites. Facebook's website is also made of PHP code.

2 years agoIf you have good knowledge of HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets), then you will not feel much difficulty in learning PHP. If you want to work on PHP then you must also know about Database Management System. PHP supports different types of databases, such as MySQL, Oracle, Sybase, SQLite, MS-Access, Informix etc.

PHP language is a very easy language that anyone can learn easily. And its biggest advantage is that it can be easily integrated with any html language or with any popular database language. Another advantage of this is that this language can encrypt and decrypt your data. And like html and java script, your source code is not visible in any browser, due to which it also becomes a very secure language.

1 year agoPHP scripts are executed on the server. It is free to download and use. PHP is an amazing and popular language. It is powerful enough to be at the core of the biggest blogging system on the web (WordPress). It is deep enough to run large social networks. It is also easy enough to be a beginner's first server-side language!

Most popular example is Facebook, which was built with PHP from start, but now have added more. Still they are using Php in some places. It was the popular language in 20s and still exist but used less now.
