PHP stands for Hypertext Preprocessor, which is an HTML-embedded scripting language originally created by Rasmus Lerdorf in 1995. It was designed for the use of web developers to allow them to create dynamic web pages and to make them more interactive & lively. It formerly stood for Personal Home Page. Much of its syntax is borrowed from C, Java and Perl with a couple of unique PHP-specific features. Now, PHP is widely used by web developers as it has many unique and advanced features. Web developers choose PHP over other alternatives as it has many reasons to differentiate itself from its competitors, like -

- PHP 4 or PHP parser compiles input to produce byte code for processing by the Zend Engine, giving a whole new improved performance.
- It also supports multiple databases like MS Access, SQL Server, My SQL and Oracle.
- Over 20 million internet domains have web services hosted on servers with PHP involved, hence emerged as the most popular Apache HTTP Server module.
- PHP can be deployed on almost every operating system today.

PHP has many versions like PHP 1, PHP 2, PHP 3, PHP 4 and PHP 5 among others. Every version of PHP comes with all new and exciting features. At present, PHP does not have native support for Unicode or multibyte strings because it is under development for a future version of PHP. This Unicode support will allow strings as well as class, method, and function names to contain non-ASCII characters.
